detailed description

The following will clearly and completely describe the technical solutions in the embodiments of the application with reference to the drawings in the embodiments of the application. Apparently, the described embodiments are only some of the embodiments of the application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

The terms "first" and "second" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance or implicitly specifying the quantity of indicated technical features. Thus, a feature defined as "first" and "second" may explicitly or implicitly include one or more of these features. In the description of the present application, unless otherwise specified, "plurality" means two or more.

At present, NFC technology has been gradually extended to miniaturized electronic devices. Electronic devices that support NFC functions, such as mobile phones, can exchange data with NFC card readers when they are close to NFC card readers (such as point of sale (POS) machines), thereby realizing various NFC card readers. Functions, such as card swiping, data transfer, etc. For example, as shown in Figure 1, mobile phone 101 has NFC function, and the user can put mobile phone 101 close to the NFC card reader 102 on the bus when taking a bus, so that mobile phone 101 can communicate with the NFC card reader 102 on the bus. Perform data exchange, that is, the mobile phone 101 completes the payment of the bus fare.

Generally, an electronic device supporting an NFC function may include an application program (eg, called an NFC application) for implementing short-distance communication. The NFC application has an emulation function of emulating a contactless integrated circuit (integrated circuit, IC) card. For example, NFC applications may include card package applications, bus applications, banking applications, access control applications, and the like.

Each NFC application includes at least one virtual card, such as a virtual transportation card, a virtual access control card, and a virtual bank card. Each virtual card may correspond to an identifier, and the identifier may be an application program identifier (applet identifier, AID) or an identifier (identity, ID). When the virtual card supports AID identification, the virtual card can be identified by the AID. And some virtual cards do not support AID identification, such as Mifare series cards, such as residential access control cards, can be identified by ID. The mapping relationship between the virtual card and the identification of the NFC application can be stored in the memory of the electronic device, and can also be stored in the cloud. As an example, assume that the above mapping relationship is stored in the memory of the electronic device, and the NFC application is a card package application as an example. Table 1 shows the mapping relationship between the virtual card and the identifier of the card package application stored in the memory of the electronic device.

Table 1

According to Table 1, in the electronic device, the card package application may include multiple virtual cards of different types, such as community access control cards, public transport cards and smart door lock cards. At the same time, the activation status of one of the multiple virtual cards is activated, for example, the activation status of the smart door lock card identified as AID2 is activated.

When the electronic device receives the NFC field strength information (that is, the electronic device is close to an NFC card reader), the electronic device defaults to the activated virtual card for data interaction with the nearby NFC card reader (that is, completes the transaction). On the activated virtual card, often the pre-configured default card. When the NFC card reader matches the default card, the data exchange between the NFC card reader and the electronic device can be successful. However, when the NFC card reader does not match the default card, data interaction failure will occur. When the NFC card reader does not match the default card, the user needs to manually select the correct virtual card to achieve successful interaction with the NFC card reader.

For example, take the electronic device as a mobile phone as an example. As shown in (a) in FIG. 2 , the default card in the card package application of the mobile phone is a smart door lock card, that is, the virtual card in an activated state is a smart door lock card. When the mobile phone is close to the NFC card reader of the bus, the mobile phone can receive instruction information including the identification (eg, AID1). After that, the mobile phone can use the default card to exchange data with the NFC card reader on the bus. If the user starts the card package application of the mobile phone at this time, the mobile phone can display the card swiping interface 201 shown in (b) in FIG. Data interaction. Of course, it is also possible that the screen of the mobile phone is turned on in response to the received instruction information, and displays the interface of the card package application, for example, the above-mentioned card swiping interface 201 is displayed. In addition, the mobile phone can also compare whether the identifier (ie, AID1) in the indication information is the same as that of the default card (ie, AID2). When the mobile phone determines that the two are different, it can display the card swiping interface 202 as shown in (c) in FIG. Afterwards, the user can manually select the correct virtual card to activate. For example, the mobile phone receives the user's selection operation on the public transportation card, and in response, the smart door lock card that is currently activated can be deactivated and the public transportation card can be activated. After that, when the mobile phone is close to the NFC card reader on the bus again, use the activated public transportation card to interact with the NFC card reader on the bus to perform operations such as deduction of the amount, and notify the NFC card reader on the bus to finish swiping the card. Generally, after swiping the card, the mobile phone can also deactivate the public transportation card and reactivate the default card (ie, the smart door lock card).

It can be seen from this that when the NFC card reader does not match the currently activated virtual card, such as the default card, that is, when faced with different card swiping requirements, the user needs to manually select the correct virtual card to activate in order to complete the activation with the NFC card reader. data interaction. Like this, cause comparatively loaded down with trivial details of the card swiping process, the time is longer.

In related technologies, a wireless fidelity (Wi-Fi) geo-fence is used to realize automatic activation of a corresponding virtual card before a user swipes the card.

Geo-fence means that when the user arrives near a certain geographical location, the user's mobile phone can monitor the longitude and latitude coordinates of the mobile phone, the logo of the cell base station scanned by the mobile phone, or the Wi-Fi information (such as Wi-Fi ID), and match with the location information corresponding to the geographic location, the ID of the cell (Cell) base station or Wi-Fi information, and after the matching is successful, the mobile phone can determine that the user enters the geofence corresponding to the geographic location.

Geofences can be classified into global navigation satellite system (global navigation satellite system, GNSS) geofences, cell (Cell) geofences, and Wi-Fi geofences according to their monitoring parameters.

The GNSS geographic fence monitoring parameter may be the latitude and longitude coordinates of the mobile phone. The monitoring area of the GNSS geo-fence can be a circular area with a certain geographic location coordinate point as the center and a certain length as the radius, or a polygonal area with multiple geographic location coordinate points as vertices and connected vertices.

The monitoring parameter of the Geographical Fence of the Cell may be the identity of the base station of the cell scanned by the mobile phone. The monitoring area of the Cell geo-fence may be the coverage area of one or more cell base station signals.

The monitoring parameter of the Wi-Fi geo-fence may be the Wi-Fi signal scanned by the mobile phone. The monitoring area of the Wi-Fi geo-fence may be the coverage area of one or more Wi-Fi signals.

After the mobile phone determines that the user enters the geographic fence corresponding to the geographic location, the fence mechanism corresponding to the geographic location can be triggered to perform operations corresponding to the fence corresponding to the geographic location, for example, the card corresponding to the geographic location can be activated.

Specifically, the solution of the above-mentioned related technology is: when a user uses a virtual card to conduct a transaction, the mobile phone sets a Wi-Fi geo-fence according to the identity of the virtual card and the Wi-Fi identity corresponding to the location where the user swipes the card, and saves the Wi-Fi - Correspondence between the Wi-Fi ID in the Fi geofence and the virtual card ID. Afterwards, the mobile phone can periodically obtain the Wi-Fi identification of the current geographical location of the mobile phone, and judge whether the obtained Wi-Fi identification is the same as the Wi-Fi identification in the set Wi-Fi geo-fence. When the mobile phone detects that the obtained Wi-Fi identifier is the same as the Wi-Fi identifier in the Wi-Fi geo-fence, it is determined that the user has entered the Wi-Fi geo-fence. At this time, the mobile phone can automatically activate the virtual card corresponding to the Wi-Fi geo-fence according to the saved correspondence, so that the user can use the activated virtual card to complete card swiping. That is, the automatic activation of the corresponding virtual card is realized before the user swipes the card.

However, the implementation of the above solution requires the mobile phone to have the capability of Wi-Fi geo-fencing, for example, the sensor hub (sensorhub) in the mobile phone is required to have the capability of low-power Wi-Fi geo-fencing. When the mobile phone does not have the Wi-Fi geo-fence capability, the setting of the virtual card corresponding to the Wi-Fi geo-fence cannot be realized, and the corresponding virtual card cannot be automatically activated before the user swipes the card. In this way, the user still needs to manually select the correct virtual card for activation.

In view of the above problems, the embodiment of the present application provides a virtual card switching method, which should be applied to electronic devices. This method can be used according to the current GNSS position information of the electronic device when the user completes the transaction with a certain virtual card at a certain card swiping point for the first time. Establish the GNSS geofence corresponding to the virtual card. Later, when the user enters the GNSS geofence again with the electronic device, the electronic device can automatically activate the virtual card corresponding to the GNSS geofence, so that the user can use the virtual card to complete transactions. That is, before the user swipes the card, the electronic device can automatically activate the corresponding virtual card by using the GNSS geo-fence.

In this way, when faced with different card swiping requirements, the user can avoid the need to manually select a virtual card, thereby reducing the time for swiping a card and improving user experience. Moreover, the solution of the present application can establish a corresponding geographic fence according to the GNSS position information, and the GNSS position information can be obtained by using the short-distance chip of the electronic device. The short-distance chip is a standard configuration of electronic equipment, so even if the electronic equipment does not have the Wi-Fi fence capability, it can still realize the automatic activation of the corresponding virtual card before the user swipes the card, further improving the user experience.

It can be understood that GNSS may include global positioning system (global positioning system, GPS), global navigation satellite system (global navigation satellite system, GLONASS), Beidou satellite navigation system (beidou navigation satellite system, BDS), quasi-zenith satellite system (quasi-zenithsatellite system, QZSS) and/or satellite based augmentation system (satellite based augmentationsystems, SBAS), etc. Therefore, the GNSS geo-fence in this embodiment may be a GPS geo-fence, a GLONASS geo-fence, a Beidou geo-fence, a QZSS geo-fence, or an SBAS geo-fence.

The specific type of the GNSS geo-fence is not limited in this application. For ease of understanding, in the following embodiments of the present application, a GNSS geofence is taken as an example for schematic illustration. That is, the monitoring parameters of the GPS fence can be the latitude and longitude coordinates of the electronic equipment. The monitoring area of the GPS fence can be a circular area with a certain geographic location coordinate point as the center and a certain length as the radius, or a polygonal area with multiple geographic location coordinate points as vertices and connected vertices.

In addition, in some examples, the above-mentioned electronic devices may be mobile phones, tablet computers, handheld computers, personal computers (personal computers, PCs), cellular phones, personal digital assistants (personal digital assistants, PDAs), wearable devices, etc. functional electronic devices.

Of course, it can be understood that what is shown in FIG. 3 above is only an exemplary description when the form of the electronic device is a mobile phone. If the electronic device is in the form of a tablet computer, a handheld computer, a PC, a PDA, a wearable device (such as a smart watch, a smart bracelet), etc., the structure of the electronic device may include fewer The structures may also include more structures than those shown in FIG. 3 , which is not limited here.

It can be understood that, generally speaking, the realization of the functions of electronic equipment requires not only the support of hardware, but also the cooperation of software.

For example, in some examples of the present application, as shown in FIG. 4, at least a processor is required to realize the automatic switching of the virtual card of the electronic device, such as a sensor hub (sensorhub), a short-distance chip, and a baseband processor (also called Baseband chip) and other hardware support, also need to use fence applications, such as NFC card package applications (such as smart flash card applications) and applications in system services (such as GPS applications, Wi-Fi applications) and other software. The software and hardware can be connected through the hardware connection layer.

Wherein, based on what is shown in Figure 4, taking the application in the system service as a GPS application and the geofence established by the electronic device as a GPS fence as an example, the process for the electronic device to automatically switch virtual cards may include: When a virtual card is used for the first time to complete a transaction, the short-range chip obtains GPS location information. The short-distance chip sends GPS positioning information to the smart flash card application through the sensorhub, hardware connection layer and GPS application. The smart flash card application builds a GPS fence and sends the built GPS fence to the GPS application. The GPS application stores and manages the fence established by the smart flash card application. The GPS application sends the established GPS fence to the sensorhub through the hardware connection layer. After that, sensorhub can periodically obtain the GPS positioning information of the electronic device from the short-range chip. The sensorhub can include fence algorithms, such as GPS fence algorithms, cell fence algorithms, and Wi-Fi fence algorithms. The sensorhub obtains the GPS location information from the short-distance chip, and uses the built-in fence algorithm, such as the GPS fence algorithm to determine whether the user enters the GPS fence. The sensorhub does not need to wake up the main processor of the electronic device when it is working, so as to realize the low-power fence capability. When sensorhub determines that the user enters the GPS fence, sensorhub sends the GPS fence that the user entered to the smart flash card application through the hardware connection layer and the GPS application, so that the smart flash card activates the virtual card corresponding to the GPS fence that the user enters .

The above example is illustrated by taking the processor of the electronic device including a sensorhub and the short-range chip as an example, that is, the short-range chip can be used to obtain GPS positioning information, and can also be used to obtain Wi-Fi scanning information. In another embodiment, the processor of the electronic device may not include a sensorhub, and the short-distance chip may include two chips, namely a GPS chip and a Wi-Fi chip, the GPS chip is used to obtain GPS positioning information, and the Wi-Fi The chip is used to obtain Wi-Fi scanning information, as shown in Figure 5, continue to take the application in the system service as the GPS application, and the fence established by the electronic device as the GPS fence as an example, the process of the electronic device to realize the automatic switching of the virtual card can be Including: when a user completes a transaction with a virtual card at a certain card swiping point for the first time, the GPS chip obtains GPS positioning information. The GPS chip sends the GPS positioning information to the smart flash card application through the hardware connection layer and the GPS application. The smart flash card application builds a GPS fence and sends the built GPS fence to the GPS application. The GPS application stores and manages the fence established by the smart flash card application. The GPS application sends the established GPS fence to the GPS chip. Afterwards, the GPS chip can periodically obtain GPS positioning information, and use its included GPS fence algorithm to determine whether the user enters the GPS fence. When it is determined that the user enters the GPS fence, the GPS chip sends the GPS fence that the user entered to the smart flash card application through the GPS application. The GPS chip can work independently without waking up the main processor of the electronic device, thereby realizing low-power fence capability . According to the GPS fence that the user enters, the smart flash card activates the virtual card corresponding to the GPS fence.

The virtual card switching method provided by the embodiment of the present application will be described in detail below with reference to FIG. 4 . Wherein, in the embodiment of the present application, the method may include: a "fence establishment" process and a "virtual card switching" process.

As shown in Fig. 6, the "fence establishment" process may include the following S601-S605.

S601. The smart flash card application of the electronic device acquires a first virtual card.

When the user needs to use the virtual card on the electronic device, he can open a virtual card on the electronic device, such as the smart flash card application of the electronic device. For example, the user may click on the option to activate immediately in the smart flash card application of the electronic device. In response to the user's click operation, the electronic device displays virtual card options that can be activated, such as public transportation card options. After that, the user can select the public transportation card and select the corresponding activation area. In response to the user's selection operation, the electronic device successfully opens a public transportation card.

After the virtual card is opened on the electronic device, the electronic device, such as the smart flash card application of the electronic device, can obtain the first virtual card, and the first virtual card can be the virtual card opened by the electronic device.

Electronic devices with NFC functions can include multiple virtual cards, such as community access cards, public transportation cards, smart door lock cards, and corresponding virtual cards for luggage, car keys, and ID cards, so as to meet different card swiping needs.

For the virtual cards in the electronic device, when the user uses any virtual card to conduct transactions, the electronic device can establish a corresponding geographic fence. A virtual card can establish one geo-fence or multiple geo-fences. For example, when the user uses a public transportation card to swipe the card at bus stop A, the electronic device may establish a geographic fence corresponding to the public transportation card at bus stop A. When the user uses the public transportation card to swipe the card at the bus station B, the electronic device may establish a geographic fence corresponding to the public transportation card at the bus station B.

Among the above-mentioned virtual cards, some of the virtual cards have fixed card swiping points. This virtual card is called the first virtual card of a predetermined type in this embodiment, such as community access control cards, public transportation cards, and smart door lock cards. The card swiping points are generally fixed. However, the swiping points of some virtual cards are indeed not fixed, such as virtual cards corresponding to car keys, bags, and ID cards. The swiping points of these virtual cards may change with different places of use.

In some embodiments, since the geo-fence needs to be established at a fixed location, a corresponding geo-fence may be established for a virtual card with a fixed swiping point, that is, the first virtual card of a predetermined type. As for the virtual card whose card swiping point is not fixed, the electronic device cannot establish a geographic fence corresponding to the virtual card because the card swiping point is not fixed. Therefore, before the electronic device establishes the geographic fence corresponding to the virtual card, the electronic device, such as the smart flash card application of the electronic device, can first determine the virtual card with a fixed swiping point according to whether the swiping point of the virtual card is fixed, that is, the first type of the predetermined type. A virtual card, so that when the electronic device first uses a predetermined type of first virtual card to complete a transaction at a certain card swiping point, it can establish a geo-fence corresponding to the predetermined type of first virtual card.

In some examples, the electronic device may determine whether the virtual card is a first virtual card of a predetermined type according to the type of the virtual card. For example, if the swipe point of the community access control card is a community, the location of the swipe point is fixed, so when the type of the virtual card is a community access card, the electronic device can determine that the swipe point of the virtual card is fixed, that is, the community access card is a first virtual card of a predetermined type.

The card swiping point of the virtual card corresponding to the ID card can be a bank, a company, or a home, that is, the position of the card swiping point of the virtual card corresponding to the ID card is not fixed. When the virtual card is selected, the electronic device may determine that the virtual card is not the first virtual card of the predetermined type.

In some embodiments, after the electronic device determines the first virtual card of the predetermined type, the electronic device, such as the smart flash card application in the electronic device, may save the identification (such as AID or ID) of the first virtual card of the predetermined type in the corresponding list.

For example, as shown in FIG. 4 , the smart flash card application of the electronic device can determine the virtual card with a fixed swiping point, that is, the first virtual card of a predetermined type, and store the identifier corresponding to the first virtual card of the predetermined type in the smart flash card list. Afterwards, the electronic device, such as the smart flash card application of the electronic device, can determine whether to establish a corresponding geo-fence corresponding to the first virtual card according to the list. For example, when a user completes a transaction with a predetermined type of first virtual card in the smart card list at a certain card swiping point for the first time, the smart card application of the electronic device may establish a geo-fence corresponding to the first virtual card. When the user completes the transaction with a virtual card in the non-smart flash card list, the smart flash card application of the electronic device does not need to establish a geo-fence.

Wherein, the process of establishing a geographic fence by the smart card application of the electronic device may include the following S602-S605.

S602. The smart flash card application of the electronic device obtains the current geographic location information and geographic location accuracy of the electronic device when a certain first virtual card is used to complete data interaction with the NFC card reader at a certain card swiping point for the first time.

When the user uses the above-mentioned first virtual card (such as the first virtual card of the above-mentioned predetermined type) to complete the transaction at a certain card-swiping point for the first time, that is, when the first virtual card is used to complete the data interaction with the NFC card reader corresponding to a certain card-swiping point , the electronic device, such as the smart flash card application of the electronic device, may establish a geographic fence corresponding to the first virtual card.

The geo-fence corresponding to the first virtual card may be at least one of a GNSS geo-fence, a Cell geo-fence, or a Wi-Fi geo-fence. The GNSS geo-fence may include GPS geo-fence, GLONASS geo-fence, Beidou geo-fence, QZSS geo-fence or SBAS geo-fence, etc. The specific type of the GNSS geo-fence is not limited in this application.

For ease of understanding, in the following embodiments of the present application, a GNSS geo-fence is taken as a GPS geo-fence (hereinafter referred to as the GPS geo-fence) as an example for schematic illustration, that is, the geo-fence corresponding to the first virtual card is a GPS fence. Correspondingly, obtaining the current geographic position information of the electronic device by the electronic device may be obtaining the current GPS position information of the electronic device, and the current GPS position information of the electronic device may be the first GNSS position information in the embodiment of the present application. Acquiring the current geographic position accuracy of the electronic device by the electronic device may be obtaining the current GPS accuracy of the electronic device, and the current GPS accuracy of the electronic device may be the first GNSS accuracy in this embodiment of the present application.

When the electronic device uses the first virtual card to complete the data interaction with the NFC card reader corresponding to a certain card swiping point, the electronic device, such as the smart flash card application of the electronic device, can obtain the current GPS location information and GPS accuracy of the electronic device, so that A GPS fence corresponding to the first virtual card is established according to the current GPS location information and GPS accuracy of the electronic device.

Among them, the electronic device, such as the smart flash card application of the electronic device, can determine whether the user at a certain card swiping point manually selects a certain first virtual card from a plurality of first virtual cards to complete the transaction. The first virtual card is used to complete the transaction for the first time.

It can be understood that the electronic device may include multiple first virtual cards. When the user swipes the card for the first time at a certain card swiping point, the user can manually select the first virtual card to be used from the multiple first virtual cards, so that the electronic device can The transaction is completed using the first virtual card selected by the user. That is, when the user manually selects the first virtual card that needs to be used from multiple first virtual cards to complete the transaction, the electronic device, such as the smart flash card application of the electronic device, can determine that the first virtual card is used for the first time at the card swiping point to complete the transaction. trade. For example, as shown in (c) in FIG. 2 , the first virtual card in the mobile phone includes a smart door lock card, a community access control card, and a public transportation card. When a user takes a bus at a bus station for the first time, the user can manually choose to use the public transportation card to complete the transaction among the community access control card, public transportation card and smart door lock card, that is, the mobile phone can determine that the user is at the bus station for the first time. Use this public transport card to complete the transaction.

When a user uses an electronic device to complete a transaction with a first virtual card at a certain card swiping point for the first time, that is, when the first virtual card completes data interaction with the NFC card reader, the electronic device, such as the smart flash card application in the electronic device, can Acquire current GPS location information of the electronic device, such as latitude and longitude coordinates, and GPS accuracy (accuracy, acc). When the user moves with the electronic device, the GPS location information of the electronic device is the GPS location information of the user.

GPS accuracy, defined as the radius with 68% confidence. In other words, the confidence level refers to the probability that the real position of the electronic device when swiping the card is located in a circular area centered on the current latitude and longitude coordinates of the electronic device obtained by the electronic device and with x times the GPS accuracy as the radius, where x is A real number greater than zero. This probability satisfies Formula 1 below.

Formula one:

Among them, erf is the Gaussian error function, erf(x) is the confidence level, x is the multiple of GPS accuracy, and t is the integral variable, which can be regarded as any real number between 0 and x, and is used to calculate the integral result without any actual meaning.

When x=1, erf(1)=0.68, that is, a circular area with the longitude and latitude coordinates obtained by the electronic device as the center and the GPS accuracy as the radius, and the probability that the real position of the electronic device is located in the circular area when swiping the card is 68%.

For example, in combination with the example in Figure 4, at a certain card swiping point, when the smart card application determines that the user manually selects a first virtual card from multiple first virtual cards to complete the transaction, the smart card application can use the system service The application (such as GPS application), hardware connection layer and sensorhub in the application (such as GPS application), obtain GPS location information and GPS accuracy from the short-range chip. Specifically, the above S602 may include the following S6021-S6028.

S6021. The smart flash card application determines that a certain first virtual card is used to complete data interaction with the NFC card reader at a certain card swiping point for the first time.

S6022. The smart flash card application sends an acquisition notification to the GPS application.

The acquisition notification is used to instruct the GPS application to acquire the current GPS location information and GPS accuracy of the electronic device.

S6023. The GPS application sends an acquisition notification to the sensor hub.

After the GPS application receives the acquisition notification, it can send the acquisition notification to the sensorhub through the hardware connection layer.

S6024. The sensor hub sends an acquisition notification to the short-distance chip.

After sensorhub receives the acquisition notification, it can send the acquisition notification to the short-distance chip.

S6025. The short-distance chip sends the current GPS position information and GPS accuracy of the electronic device to the sensor hub.

After the short-distance chip receives the acquisition notification, it can send the current GPS location information and GPS accuracy of the electronic device to the sensorhub.

S6026. The sensor hub sends the current GPS location information and GPS accuracy of the electronic device to the GPS application.

After sensorhub receives the current GPS location information and GPS accuracy of the electronic device, it can send the current GPS location information and GPS accuracy of the electronic device to the GPS application through the hardware connection layer.

S6027. The GPS application sends the current GPS location information and GPS accuracy of the electronic device to the smart flash card application.

S6028. The smart flash card application receives current GPS location information and GPS accuracy of the electronic device.

S603. The smart flash card application of the electronic device establishes a first geo-fence corresponding to the first virtual card according to the current geographic location information and geographic location accuracy of the electronic device.

As described in the foregoing embodiment, the first geo-fence corresponding to the first virtual card may be a GNSS geo-fence, a Cell geo-fence, a Wi-Fi geo-fence, or other types of geo-fences. This application The embodiment does not limit this. The GNSS geo-fence can be GPS geo-fence, GLONASS geo-fence, Beidou geo-fence, QZSS geo-fence or SBAS geo-fence. The specific type of the GNSS geo-fence is not limited in this application.

For ease of understanding, in this application, the first geographical fence corresponding to the first virtual card is a GPS fence (that is, the first GPS fence) as an example for schematic illustration. Correspondingly, when the geographic fence is a GPS fence, the geographic location information may be GPS location information, and the geographic location accuracy may be GPS accuracy.

The first GPS fence corresponding to the first virtual card may be a circular area with the acquired GPS location information as the center and a preset length as the radius. For example, as shown in Figure 4, after the electronic device, such as the smart flash card application of the electronic device, obtains the GPS location information and GPS accuracy, the smart flash card application can establish the first GPS location information as the center and the corresponding length as the radius. A GPS fence, the first GPS fence corresponds to the first virtual card.

It can be understood that when the radius of the GPS fence is too large, overlapping areas tend to exist among different GPS fences. However, when the user enters the overlapping area with the electronic device, the electronic device cannot determine which virtual card corresponding to the GPS fence will be activated. When the radius of the GPS fence is too small, the real location of the user when swiping the card may be outside the GPS fence, so that the electronic device cannot automatically select the correct virtual card and activate it before the user swipes the card.

Therefore, in the embodiment of the present application, the electronic device, such as the smart flash card application of the electronic device, can dynamically determine the size of the GPS fence corresponding to the established first virtual card according to the GPS position information and GPS accuracy (that is, dynamically determine the size of the first virtual The radius of the GPS fence corresponding to the card), so that there is no overlapping area between the established GPS fence corresponding to the first virtual card and other GPS fences. Specifically, as shown in FIG. 7, the above S603 may include the following S701-S710.

S701. The smart flash card application of the electronic device establishes an initial geo-fence corresponding to the first virtual card according to the current geographic location information of the electronic device and a preset length.

As described in the foregoing embodiment, the initial geo-fence corresponding to the first virtual card may be a GNSS geo-fence, a Cell geo-fence, a Wi-Fi geo-fence, or other types of geo-fences. The example does not limit this. The GNSS geo-fence can be GPS geo-fence, GLONASS geo-fence, Beidou geo-fence, QZSS geo-fence or SBAS geo-fence. The specific type of the GNSS geo-fence is not limited in this application.

For ease of understanding, in the following embodiments of the present application, the initial geographic fence corresponding to the first virtual card is taken as an example for schematic illustration.

Since the radius of the GPS fence established by the electronic device is larger, the real position of the user when using the first virtual card for transactions is more likely to be within the range of the GPS fence, which can avoid the occasional GPS positioning drift that causes the electronic device to use the first virtual card. The real location of the card for transaction is outside the established GPS fence range, so as to ensure that the electronic device can automatically activate the corresponding virtual card before the user swipes the card.

Therefore, when the electronic device, such as the smart flash card application of the electronic device, establishes the GPS fence corresponding to the first virtual card, it can first establish the initial GPS fence corresponding to the first virtual card with a larger radius.

The radius of the initial GPS fence corresponding to the first virtual card may be a preset length. The size of the preset length can be set according to actual conditions, which is not limited in this embodiment of the present application. For example, the preset length may be 2 kilometers. That is, the initial GPS fence corresponding to the first virtual card is a circular area centered on the current GPS location information acquired by the electronic device and with a radius of 2 kilometers.

S702. The smart flash card application of the electronic device determines whether there is an overlapping area between the initial geo-fence and the second geo-fence.

After the electronic device establishes the initial geographic fence corresponding to the first virtual card, such as the initial GPS fence, the electronic device, such as the smart flash card application of the electronic device, can determine whether the initial GPS fence and the geographic fence that has been established and stored in the electronic device exist overlapping area.

The geofence established and stored in the electronic device (such as the second geofence) can be a GNSS geofence, a Cell geofence, a Wi-Fi geofence, or other types of geofences. This embodiment of the present application does not limit it. The GNSS geo-fence can be GPS geo-fence, GLONASS geo-fence, Beidou geo-fence, QZSS geo-fence or SBAS geo-fence. The specific type of the GNSS geo-fence is not limited in this application.

In order to facilitate understanding, in the following embodiments of the present application, the geographical fence established and stored in the electronic device is taken as a GNSS fence as an example for schematic illustration. The established and stored GNSS fence can be the second GNSS fence in the embodiment of the present application. The fence in the second GNSS fence that overlaps with the initial GNSS fence may be the third GNSS fence in the embodiment of the present application. There can be one or more third GNSS fences. For ease of understanding, in the following embodiments of the present application, the geographical fence that has been established and stored in the electronic device is a GPS fence (for example, called the second GPS fence) as an example for schematic illustration. The second GPS fence can be a GPS fence (such as called a third GPS fence).

The second GPS fence can be a circular area centered on the GPS location information obtained by the electronic device when the electronic device completes the transaction at the card swiping point corresponding to the second GPS fence, and taking the corresponding length as the radius. The corresponding length can be the above-mentioned preset length, such as 2 kilometers, or other lengths, such as a dynamically determined length based on the acquired GPS location information, GPS accuracy, and the GPS location information and GPS accuracy of other GPS fences .

Electronic devices, such as smart flash card applications for electronic devices, can be based on the center of the initial GPS fence (that is, the GPS location information used by the electronic device to establish the initial GPS fence, that is, the current GPS location information obtained by the electronic device), the radius of the initial GPS fence (i.e. the above-mentioned preset length), the center of the second GPS fence (that is, the GPS position information used by the electronic device to establish the second GPS fence) and the radius of the second GPS fence to determine whether the initial GPS fence and the second GPS fence exist overlapping area.

In some embodiments, the electronic device, such as the smart flash card application of the electronic device, can determine whether the distance between the center of the initial GPS fence and the center of the second GPS fence is greater than the radius of the initial GPS fence and the radius of the second GPS fence , so as to determine that there is a non-overlapping area between the initial GPS fence and the second GPS fence. When the electronic device determines that the distance between the center of the initial GPS fence and the center of the second GPS fence is less than or equal to the sum of the radius of the initial GPS fence and the radius of the second GPS fence, the smart flash card application of the electronic device can It is determined that an overlapping area exists between the initial GPS fence and the second GPS fence. When the electronic device determines that the distance between the center of the initial GPS fence and the center of the second GPS fence is greater than the sum of the radius of the initial GPS fence and the radius of the second GPS fence, the smart flash card application of the electronic device determines the initial GPS There is a non-overlapping area between the fence and the second GPS fence.

For example, it is assumed that the radius of the initial GPS fence is 2 kilometers, and the radius of the second GPS fence is 2 kilometers. The smart card application of the electronic device can determine the distance between the center of the initial GPS fence and the center of the second GPS fence. For example, the smart card application of the electronic device determines that the distance between the center of the initial GPS fence and the center of the second GPS fence is 5 kilometers, and 5 kilometers is greater than 4 kilometers, that is, the distance between the center of the initial GPS fence and the center of the second GPS fence is 5 kilometers. If the distance between the centers of the fences is greater than the sum of the radius of the initial GPS fence and the radius of the second GPS fence, the smart flash card application of the electronic device can determine that there is no overlapping area between the initial GPS fence and the second GPS fence. As another example, when the smart flash card application of the electronic device determines that the distance between the center of the initial GPS fence and the center of the second GPS fence is 3 kilometers, 3 kilometers is less than 4 kilometers, that is, the center of the initial GPS fence and the center of the second GPS fence If the distance between the centers of the two GPS fences is less than the sum of the radius of the initial GPS fence and the radius of the second GPS fence, the smart flash card application of the electronic device can determine that there is an overlapping area between the initial GPS fence and the second GPS fence.

In some embodiments, multiple second GPS fences may be included in the electronic device, and the electronic device, such as the smart flash card application of the electronic device, may determine whether there is an overlapping area between the initial GPS fence and each second GPS fence in the above manner .

When the electronic device determines that there is no overlapping area between the initial GPS fence and the plurality of second GPS fences, the electronic device may execute the following S703.

When the electronic device determines that there is an overlapping area between the initial GPS fence and one or more second GPS fences among the above-mentioned plurality of second GPS fences, the electronic device may, according to the GPS accuracy corresponding to the initial GPS fence (that is, the current GPS accuracy) and the GPS accuracy corresponding to the second GPS fence (that is, the GPS accuracy obtained by the electronic device when the second GPS fence is established), dynamically determine the radius of the first GPS fence corresponding to the first virtual card, so that the established first There is no overlapping area between the first GPS fence and the second GPS fence corresponding to a virtual card. For ease of description, the second GPS fence that overlaps with the initial GPS fence among the plurality of second GPS fences is referred to as the third GPS fence in this application. There can be one or more third GPS fences. Specifically, the electronic device may execute the following S704-S710.

S703. The smart flash card application of the electronic device uses the initial geo-fence as the first geo-fence.

In the embodiment of the present application, the initial geographical fence corresponding to the first virtual card is a GPS fence as an example for schematic illustration. It can be understood that when the initial geographic fence is a GPS fence, the first geographic fence is a GPS fence, that is, the first GPS fence.

When the electronic device determines that there is no overlapping area between the initial GPS fence and the second GPS fence, the electronic device, such as the smart flash card application of the electronic device, can use the initial GPS fence as the first GPS fence corresponding to the first virtual card, that is, the electronic The device uses the preset length as the radius of the first GPS fence. That is to say, the first GPS fence is a circular area centered on the current GPS location information of the electronic device acquired by the electronic device and with a preset length (such as 2 kilometers) as the radius.

For example, as shown in (a) in FIG. 8 , take the initial GPS fence 01 as an example, and the radius of the initial GPS fence 01 is 2 kilometers as an example. When the electronic device determines that there is no overlapping area between the initial GPS fence 01 and the second GPS fence already established in the electronic device, the electronic device can establish the first GPS fence with a radius of 2 kilometers around the current GPS location information of the electronic device. The virtual card corresponds to the first GPS fence.

S704. The smart flash card application of the electronic device determines whether there is one third geo-fence that overlaps with the initial geo-fence.

The third geo-fence may be one or more geo-fences in the second geo-fence established and stored in the electronic device. The third geo-fence may be a GNSS geo-fence, may also be a Cell geo-fence, may also be a Wi-Fi geo-fence, or may be another type of geo-fence, which is not limited in this embodiment of the present application. The GNSS geo-fence can be GPS geo-fence, GLONASS geo-fence, Beidou geo-fence, QZSS geo-fence or SBAS geo-fence. The specific type of the GNSS geo-fence is not limited in this application.

For ease of understanding, in the embodiment of the present application, the initial geographic fence corresponding to the first virtual card is a GPS fence, and the third geographic fence is a GPS fence (ie, the third GPS fence) as an example for schematic illustration.

Because the second GPS fence in the electronic device can be one or multiple. Therefore, the electronic device, such as the smart flash card application of the electronic device, may have one or more second GPS fences (that is, third GPS fences) that overlap with the initial GPS fence.

In a case where the electronic device determines that the third GPS fence is one, the electronic device may execute the following S705-S707. In a case where the electronic device determines that there are multiple third GPS fences, the electronic device may execute the following S708-S710.

S705. The smart flash card application of the electronic device acquires the center of the third geo-fence and the corresponding geographic location accuracy.

In the embodiment of the present application, the third geographical fence is a GPS fence (that is, the third GPS fence) as an example for schematic illustration. Correspondingly, the center of the third geo-fence can be the GPS position information used when setting up the third geo-fence, and the GPS position information used when the third geo-fence is established can be the second GNSS position information of the present application (such as the second GPS location information), the location accuracy of the third geo-fence may be GPS accuracy, and the GPS accuracy used when establishing the third geo-fence may be the second GNSS accuracy (such as the second GPS accuracy) of this application.

The electronic device, such as the smart flash card application of the electronic device, can acquire the center of the third GPS fence and the corresponding GPS accuracy from the memory of the electronic device.

The GPS accuracy corresponding to the third GPS fence may be the GPS accuracy obtained by the electronic device when the electronic device establishes the third GPS fence. The GPS accuracy corresponding to the third GPS fence may also be the updated GPS accuracy acquired by the electronic device when using the virtual card corresponding to the third GPS fence for transactions.

S706. The smart flash card application of the electronic device determines after the initial geo-fence is withdrawn according to the center of the initial geo-fence, the location accuracy corresponding to the initial geo-fence, the center of the third geo-fence, and the location accuracy corresponding to the third geo-fence of the radius.

In the embodiment of the present application, the initial geographic fence corresponding to the first virtual card is a GPS fence, and the third geographic fence is a GPS fence as an example for schematic illustration. Correspondingly, the center of the initial geo-fence may be the current GPS location accuracy obtained by the electronic device, the center of the third geo-fence may be the GPS location information used when establishing the third geo-fence, and the accuracy of the third geo-fence may be GPS accuracy.

When there is an overlapping area between the initial GPS fence and the third GPS fence, in order to prevent the two GPS fences from overlapping, the two GPS fences need to retreat to each other, that is, the radii of the two GPS fences should be reduced accordingly.

When the GPS accuracy is high, the electronic device can build a smaller GPS fence, which can ensure that the actual location of the user when using the first virtual card for transactions is within the established GPS fence. When the GPS accuracy is low, the electronic device needs to build a larger GPS fence, so that the actual location of the user when using the first virtual card to conduct transactions is within the established GPS fence. Therefore, the radius of the GPS fence with higher GPS accuracy can be reduced more, and the radius of the GPS fence with lower GPS accuracy can be reduced more.

Specifically, the electronic device may calculate the radius of the initial GPS fence after retreat and the radius of the third GPS fence after retreat according to the following process.

First, in order to avoid overlapping areas between the initial GPS fence and the third GPS fence, the distance between the centers of the two GPS fences should be greater than the radius of the initial GPS fence retreat (the radius of the initial GPS fence retreat can be The sum of the first radius in the embodiment of the present application) and the radius after retreat of the third GPS fence (the radius after retreat of the third GPS fence may be the second radius in the embodiment of the present application). For example, the retreated radius of the initial GPS fence and the retreated radius of the third GPS fence may satisfy the following formula two.

Formula 2: l=l _x +l _y +d;

Among them, l is the distance between the center of the initial GPS fence and the center of the third GPS fence, l _x is the radius of the initial GPS fence retreat, _ly is the radius of the third GPS fence retreat, d is the distance between the initial GPS fence and Buffer width between third GPS fence boundaries.

The size of the buffer width d can be set according to the actual situation, and the size of the buffer width d does not change with the size of the distance between the center of the initial GPS fence and the center of the second GPS fence. For example, the buffer width d may be 20 meters.

At the same time, for the GPS fence established with the radius of the initial GPS fence retreat, and the GPS fence established with the radius of the third GPS fence retreat, when the user uses the first virtual card corresponding to the initial GPS fence to conduct transactions, the user's real The probability that the location is located in the GPS fence established with the radius after the initial GPS fence retreat, and when the user uses the virtual card corresponding to the third GPS fence to conduct transactions, the user's real location is located in the radius established with the retreat of the third GPS fence The probabilities in are equal. For example, the probability that the user's real location is located in the GPS fence established with the radius of the initial GPS fence retreat, and the probability that the user's real location is located in the GPS fence established with the radius of the third GPS fence retreat can satisfy the following Formula three.

Formula three:

为用户的真实位置位于以初始GPS围栏退让后的半径建立的GPS围栏中的概率，

为用户的真实位置位于以第三GPS围栏的退让后的半径建立的GPS围栏中的概率，l_x为初始GPS围栏退让后的半径，l_y为第三GPS围栏退让后的半径，c_x为初始 GPS围栏对应的GPS精度，c_y为第三GPS围栏对应的GPS精度。in,

is the probability that the user's real location is located in the GPS fence established with the radius after the initial GPS fence retreat,

is the probability that the user's real location is located in the GPS fence established by the radius of the third GPS fence, l _x is the radius of the initial GPS fence after retreat, _ly is the radius of the third GPS fence after retreat, c _x is GPS accuracy corresponding to the initial GPS fence, _cy is the GPS accuracy corresponding to the third GPS fence.

Combining Formula 2 and Formula 3, the radius l _x of the initial GPS fence retreat can be calculated, and the radius _ly of the third GPS fence retreat can also be calculated. For example, the radius l _x of the initial GPS fence retreat may satisfy the following formula 4, and the radius _ly of the third GPS fence retreat may satisfy the following formula 5.

Formula four:

Among them, l _x is the radius after the initial GPS fence retreat, c _x is the GPS accuracy corresponding to the initial GPS fence, _cy is the GPS accuracy corresponding to the third GPS fence, l is the center of the initial GPS fence and the center of the third GPS fence The distance between, d is the buffer width between the initial GPS fence and the border of the third GPS fence.

Formula five:

Among them, l _x is the radius after the initial GPS fence retreat, c _x is the GPS accuracy corresponding to the initial GPS fence, _cy is the GPS accuracy corresponding to the third GPS fence, l is the center of the initial GPS fence and the center of the third GPS fence The distance between, d is the buffer width between the initial GPS fence and the border of the third GPS fence.

For example, shown in (b) in conjunction with Fig. 8, take initial geographic fence as initial GPS fence, the radius of initial GPS fence 01 is 2 kilometers, and the 3rd GPS fence in overlapping area with initial GPS fence 01 is an example , that is, the third GPS fence 02 is one. According to the center of the initial GPS fence 01, the GPS accuracy corresponding to the initial GPS fence 01, the center of the third GPS fence 02, and the accuracy corresponding to the third GPS fence 02, the smart flash card application of the electronic device determines the initial GPS fence 01. The radius is 600 meters and the third GPS fence 02 has a radius of 200 meters.

In some embodiments, the above-mentioned first radius may be smaller than l _x obtained by the above-mentioned formula 4, and the above-mentioned second radius may be smaller than _ly obtained by the above-mentioned formula 5.

S707. The smart flash card application of the electronic device establishes a first geo-fence corresponding to the first virtual card according to the center of the initial geo-fence and the radius after the initial geo-fence retreat.

In the embodiment of the present application, the initial geographical fence is a GPS fence as an example for schematic illustration. Correspondingly, the first geographic fence may be a GPS fence (that is, the first GPS fence).

The first GPS fence corresponding to the first virtual card may be a circular area centered on the center of the initial geographic fence (that is, the current GPS location information of the electronic device) and the radius after the initial GPS fence retreats.

In some examples, on the electronic device, the smart flash card application of the electronic device can determine the radius of the third GPS fence after retreat, for example, determine the radius of the third GPS fence after retreat according to the above formula 5. After determining the retreated radius of the third GPS fence, the electronic device may update the third GPS fence according to the retreated radius of the third GPS fence. That is, the third GPS fence is updated to be a circular area with the center of the third GPS fence as the center and the radius after the retreat of the third GPS fence as the radius.

S708. The smart flash card application of the electronic device acquires the center of each third geo-fence and the corresponding geographic location accuracy.

In the embodiment of the present application, the third geographical fence is a GPS fence (that is, the third GPS fence) as an example for schematic illustration. Correspondingly, the center of the third geo-fence may be GPS location information used when establishing the third geo-fence, and the accuracy of the third geo-fence may be GPS accuracy.

The electronic device, such as the smart flash card application of the electronic device, can obtain from the memory of the electronic device the center of each third GPS fence that overlaps with the initial GPS fence and the corresponding GPS accuracy of multiple third GPS fences.

S709. The smart flash card application of the electronic device respectively determines a plurality of corresponding initial geo-fences according to the center of the initial geo-fence, the geographic location accuracy corresponding to the initial geo-fence, the center of each third geo-fence, and the corresponding geographic location accuracy first radius.

In the embodiment of the present application, the initial geo-fence is a GPS fence and the third geo-fence is a GPS fence as an example for schematic illustration. Correspondingly, the center of the initial geo-fence may be the current GPS location accuracy obtained by the electronic device, the geographic location accuracy corresponding to the initial geo-fence may be the GPS accuracy, and the center of the third geo-fence may be the GPS position used when establishing the third geo-fence information, the location accuracy corresponding to the third geo-fence may be GPS accuracy.

When there is an overlapping area between the initial GPS fence and multiple third GPS fences, in order to prevent the initial GPS fence from overlapping with each third GPS fence, it is necessary to retreat the initial GPS fence and each third GPS fence, that is, The radius of the initial GPS fence is reduced correspondingly with each third GPS fence.

For each third GPS fence in the initial GPS fence and a plurality of third GPS fences, the electronic device, such as the smart flash card application of the electronic device, can be based on the center of the initial GPS fence, the GPS accuracy corresponding to the initial GPS fence, the third The center of the GPS fence and the GPS accuracy corresponding to the third GPS fence determine the radius after the initial GPS fence retreats, that is, the first radius. For a specific implementation manner, reference may be made to the implementation manner in S706 above, which will not be repeated in this embodiment of the present application.

S710. The smart flash card application of the electronic device determines, according to the multiple first radii, a radius after the initial geo-fence retreat.

In the embodiment of the present application, the initial geographical fence is a GPS fence (that is, the initial GPS fence) as an example for schematic illustration. Correspondingly, the first geographic fence is a GPS fence (that is, the first GPS fence).

After determining the multiple first radii, the electronic device, such as the smart flash card application of the electronic device, can determine the radius of the initial GPS fence according to the multiple first radii.

In some examples, the electronic device, such as the smart flash card application of the electronic device, may use the smallest first radius among the retracted radii of multiple initial GPS fences as the retracted radius of the initial GPS fence.

For example, there are two third GPS fences that overlap with the initial GPS fence, namely the third GPS fence 01 and the third GPS fence 02. The center of the fence 01 and the GPS accuracy corresponding to the third GPS fence 01 determine that the radius (ie, the first radius) of the initial GPS fence after retreat is 600 meters. According to the center of the initial GPS fence, the radius of the initial GPS fence, the center of the third GPS fence 02, and the GPS accuracy corresponding to the third GPS fence 02, the electronic device determines that the radius of the initial GPS fence after retreat (that is, the first radius) is 400 rice. Then the electronic device, such as the smart flash card application of the electronic device, uses 400 meters as the radius after the initial GPS fence retreat.

For example, as shown in (a) in FIG. 9 , take the initial GPS fence 01 as an example, and the radius of the initial GPS fence 01 is 2 kilometers as an example. When the electronic device determines that there is no overlapping area between the initial GPS fence 01 and the second GPS fence already established in the electronic device, the electronic device can establish the first GPS fence with a radius of 2 kilometers around the current GPS location information of the electronic device. The virtual card corresponds to the first GPS fence. As another example, as shown in (b) of FIG. 9 , it is assumed that the initial geographic fence is a GPS fence and the third geographic fence is a GPS fence. When there are two third GPS fences that overlap with the initial GPS fence 01, that is, the third GPS fence 02 and the third GPS fence 03, the electronic device calculates that the radius of the initial GPS fence 01 is 600, and the third GPS fence The radius of fence 02 after retreat is 200 meters, and the radius of third GPS fence 03 after retreat is 200 meters, that is, the distance between the initial GPS fence 01 after retreat, the third GPS fence 02 after retreat and the second GPS fence 03 after retreat There is no overlapping area between them.

After determining the radius of the first GPS fence, the electronic device, such as the smart flash card application of the electronic device, can establish the first GPS fence corresponding to the first virtual card according to the current GPS position information of the electronic device and the radius of the first GPS fence , that is, the electronic device can execute the above S707.

In some examples, for each third GPS fence in the initial GPS fence and multiple third GPS fences, the electronic device, such as the smart flash card application of the electronic device, according to the center of the initial GPS fence, the GPS corresponding to the initial GPS fence Accuracy, the center of the third GPS fence and the accuracy corresponding to the third GPS fence, after the radius of the initial GPS fence is determined, the electronic device, such as the smart flash card application of the electronic device, can be based on the center of the initial GPS fence and the third GPS fence. The distance between the centers of the GPS fences, the retracted radius of the initial GPS fence and the aforementioned buffer width determine the retracted radius of the third GPS fence. For example, taking the buffer width as 20 meters and the distance between the center of the initial GPS fence and the center of the second GPS fence as 1 kilometer as an example, the electronic device determines that the radius of the initial GPS fence is 400 meters as an example. The radius after the retreat of the third GPS fence can be 1 kilometer minus 400 meters, and then subtract 20 meters, that is, the radius after the retreat of the third GPS fence can be 580 meters.

In some examples, in order to ensure that there is no overlapping area between the first GPS fence and the third GPS fence corresponding to the first virtual card, when the electronic device determines the retreated radius of the third GPS fence, the electronic device, such as the electronic device The smart flash card application may use the smaller radius between the determined radius of the third GPS fence after retreat and the original radius of the third GPS fence as the radius of the third GPS fence after retreat. For example, continue taking the example where the buffer width is 20 meters, the distance between the center of the initial GPS fence and the center of the third GPS fence is 1 kilometer, and the electronic device determines that the radius of the initial GPS fence is 400 meters as an example . The radius after the third GPS fence retreat can be 1 kilometer minus 400 meters, and then subtract 20 meters, that is, the radius after the third GPS fence retreat can be 580 meters. If the original radius of the third GPS fence is 500 meters, the radius of the third GPS fence after retreating is still the original radius, that is, 500 meters. If the original radius of the third GPS fence is 600 meters, then the radius of the third GPS fence can be 580 meters.

In some examples, after the electronic device determines the retreated radius of each third GPS fence, the electronic device may respectively update the corresponding third GPS fence according to the retreated radius of each third GPS fence. That is, the original third GPS fence is updated to a circular area with the center of the third GPS fence as the center and the radius after the retreat of the third GPS fence as the radius.

S604. The smart flash card application of the electronic device saves the first geo-fence, the current geographic location information of the electronic device, and the geographic location accuracy.

In the embodiment of the present application, the first geographical fence is a GPS fence as an example for schematic illustration. Correspondingly, the current geographic location information of the electronic device may be GPS location information, and the current geographic location accuracy may be GPS accuracy.

After the electronic device determines the first GPS fence, that is, after determining the radius of the first GPS fence, the electronic device, such as the smart flash card application in the electronic device, can use the current GPS position information, GPS accuracy and first virtual card of the electronic device Corresponding to the first GPS fence, it is stored in the memory of the electronic device. For example, the smart flash card application of the electronic device may store the correspondence between the identifier of the first virtual card and the identifier of the first GPS fence in the memory of the electronic device. The identifier of the first virtual card may be the AID of the first virtual card, or may be the ID of the first virtual card. The identifier of the first GPS fence may be the ID of the first GPS fence. Table 2 shows the correspondence between the identifier of the first virtual card stored in the memory of the electronic device and the identifier of the first GPS fence.

Table 2

As shown in Table 2, taking the first virtual card as the community access control card as an example, the community access control card marked as ID1 corresponds to the GPS fence marked as ID2, and the center of the GPS fence corresponding to the GPS fence marked as ID2 is the electronic device current GPS location information, the GPS accuracy corresponding to the GPS fence identified as ID2 is the current GPS accuracy of the electronic device.

In some embodiments, when the electronic device has many geo-fences corresponding to the subsequently established virtual card, the electronic device can delete some of the geo-fences according to the actual situation, such as the geo-fences that have not been used within a preset period of time, Or the geo-fence whose usage period reaches the validity period, the electronic device can delete the geo-fence. Wherein, the preset duration and validity period may be set according to actual conditions. For example, take the judgment basis for deleting a geofence as whether the usage period reaches the validity period as an example. The electronic device, such as the smart flash card application of the electronic device, can determine whether the service period of the established geographic fence reaches the corresponding validity period. When the usage period of the geo-fence reaches the corresponding validity period, the electronic device, such as the smart flash card application of the electronic device, can delete the geo-fence. For example, an electronic device, such as the smart flash card application of the electronic device, can determine whether the GPS fence corresponding to the stored first virtual card has reached the corresponding validity period. When the GPS fence reaches the corresponding validity period, the electronic device, such as the electronic device The smart card application can remove the GPS fence. As another example, when the electronic device, such as the smart flash card application of the electronic device determines that there are many GPS fences corresponding to the first virtual card stored in the electronic device, the electronic device can delete some of the GPS fences according to the actual situation, such as within a preset period of time. There is no GPS fence used, the electronic device can remove the GPS fence.

Understandably, due to factors such as weather, indoors and outdoors, and user movement, the current GPS accuracy obtained by the electronic device (that is, the GPS accuracy used when establishing the first geofence corresponding to the first virtual card) is not accurate enough, resulting in the establishment of the electronic device. The accuracy of the first geographic fence corresponding to a virtual card is not high. In some instances, in order to prevent the current GPS accuracy obtained by the electronic device from being inaccurate due to factors such as weather, indoors and outdoors, and user movement, after the electronic device saves the first GPS fence, the current GPS location information of the electronic device, and the GPS accuracy, when When the electronic device uses the first virtual card to swipe the card within the range of the first GPS fence, the electronic device, such as the smart flash card application of the electronic device, can obtain the GPS accuracy when swiping the card, and use the GPS accuracy when swiping the card to update the storage of the electronic device. The current GPS accuracy. For example, the updated GPS accuracy, the GPS accuracy when swiping the card, and the current GPS accuracy stored in the electronic device satisfy the following formula six.

Formula 6: Sacc1=(a*Sacc)+((1-a)*acc);

Wherein, Sacc1 is the updated GPS accuracy, Sacc is the current GPS accuracy stored in the electronic device, a is a preset parameter, and acc is the GPS accuracy when swiping the card. The parameter a can be 0.9.

In some embodiments, the electronic device, such as the smart flash card application of the electronic device, can determine whether the current GPS accuracy acquired by the electronic device (that is, the GPS accuracy used when establishing the first geographic fence corresponding to the first virtual card) is less than the accuracy threshold, In the case that the current GPS accuracy obtained by the electronic device is less than the accuracy threshold, when the electronic device uses the first virtual card to swipe the card at the card swiping point corresponding to the first GPS fence in the subsequent (as follows) electronic device, such as the smart flash of the electronic device The card application can obtain the GPS accuracy when the card is swiped, and use the GPS accuracy when the card is swiped to update the current GPS accuracy stored in the electronic device, that is, the GPS accuracy corresponding to the first GPS fence. The accuracy threshold can be set according to actual conditions, which is not limited in this embodiment of the present application. For example, an electronic device, such as a smart flash card application of the electronic device, can obtain the updated GPS accuracy according to the above formula six.

In some embodiments, the electronic device, such as the smart flash card application of the electronic device, may periodically update the GPS accuracy corresponding to the first GPS fence stored in the electronic device. For example, the electronic device may obtain the GPS accuracy of the user's card swiping at the corresponding point of the first GPS fence every preset period of time (such as 1 week or 1 month), and update the first GPS fence corresponding to the first GPS fence stored in the electronic device according to the GPS accuracy. The current GPS accuracy. For example, the electronic device, such as the smart flash card application of the electronic device, can obtain the updated GPS accuracy according to the above formula six.

In some embodiments, the electronic device, such as the smart flash card application of the electronic device, can also update the GPS accuracy corresponding to the first GPS fence stored in the electronic device after detecting that the trigger condition is reached (that is, establish the first virtual card corresponding to the first GPS precision used when a geofence is used) or current GPS location information of the electronic device (that is, the GPS location information used when establishing the first geofence corresponding to the first virtual card). The trigger condition may include that the position of the swiping point corresponding to the first GPS fence changes. For example, the card swiping point corresponding to the first GPS fence is a bus stop, because the position of the bus stop changes from position A to position B, and the distance between position A and position B is less than the preset distance. When the electronic device detects that the public transportation card is used to swipe the card at position B, the electronic device can determine that the position of the card swiping point corresponding to the first GPS fence changes from position A to position B, that is, the electronic device can determine that the trigger condition is reached, and the electronic device For example, the smart card application of the electronic device can obtain the GPS location information and GPS accuracy corresponding to location B, and update the GPS location information and GPS accuracy corresponding to the first GPS fence stored in the electronic device.

It can be understood that after the electronic device updates the GPS accuracy or GPS location information corresponding to the first GPS fence of the first virtual card, the electronic device, such as the smart flash card application of the electronic device, can , re-establish the GPS fence corresponding to the first virtual card, and update the first GPS fence stored in the electronic device. For the process of the electronic device re-establishing the GPS fence corresponding to the first virtual card, reference may be made to the above-mentioned steps S601-S604, which will not be repeated in this embodiment of the present application.
