The following describes in detail the NFC card activation method provided by the embodiment of the present application through a specific embodiment and an application scenario thereof with reference to the accompanying drawings.
Referring to fig. 1, fig. 1 is one of flowcharts of an NFC card activation method provided by an embodiment of the present application, which is executed by a first electronic device, as shown in fig. 1, and the method includes:
step 101, acquiring first non-connection parameters corresponding to N NFC cards in a security chip of a first electronic device, wherein the first non-connection parameters comprise first parameters and activation parameters, and N is a positive integer.

In addition, the application can also be used in the application scenes such as cards, keys and the like which use Bluetooth, wireless fidelity (WIRELESS FIDELITY, WIFI), ultra Wideband (UWB) and other modes as communication technologies.
The first non-connection parameter is a non-connection parameter of an NFC card stored in the security chip, where the non-connection parameter of the NFC card mainly includes a first parameter and an activation parameter, and the first parameter mainly includes an identity identifier UID, a selection acknowledgement (Select acknowledge, SAK), a frame waiting time (FRAME WAITING TIME INTEGER, FWI), a Start frame protection time (Start-up frame guard time, SFGI), and a selection response (ATS), and the identity identifier may be a physical card number corresponding to the NFC card, which is a unique identifier of the NFC card. The first non-connection parameters of the NFC card comprise first parameters and activation parameters, the activation parameters are priorities of the first parameters, the priorities mainly comprise high priorities and low priorities, the high priorities can be represented by 'F', and the low priorities can be represented by '0'.
Step 102, adjusting the activation parameters of each NFC card to preset activation parameters.
The preset activation parameters are activation parameters corresponding to low priority.

Therefore, when a plurality of NFC cards exist in the first electronic device, all the NFC cards in the security chip can be activated according to the preset activation parameters, so that the probability of failure in activating the NFC cards can be reduced.
In an alternative embodiment, after the activating the N NFC cards, the method further includes:

The NFC chip can be used as an antenna to exchange data with the second electronic device, and information of non-connection parameters of the NFC cards related to the transaction can be determined under the condition that the NFC chip stores the non-connection parameters of the plurality of NFC cards.

Meanwhile, in the NFC chip, the priority of the second non-connection parameter of the NFC card is a priority preset by the NFC card, the priority of the first NFC card is "F", the priority of the second NFC card is "F", the priority of the third NFC card is "F", and the priority of the fourth NFC card is "0".

According to the second non-connection parameters stored in the NFC chip, a first target NFC card in N NFC cards for card swiping transaction can be determined. The second electronic device is an electronic device with a Point of sale information management system (POS), and may be referred to as a POS machine.

The method comprises the steps that a first electronic device obtains a verification request sent by a second electronic device, the second electronic device sends a transaction instruction to the first electronic device after verification is passed, further, the second electronic device can determine target non-connection parameters matched with the verification request in second non-connection parameters, further, an NFC chip informs a security chip of NFC cards corresponding to the target parameters, among N NFC cards of the security chip, the NFC card comprising the target non-connection parameters is determined to be a first target NFC card used for transaction, and finally, card swiping transaction is conducted through the first target NFC card in response to the verification request.
In addition, all NFC cards in the secure chip have been activated, and all NFC cards can complete transactions with their respective second electronic devices during different time periods.

And determining the NFC card comprising the target non-connection parameters as a first target NFC card in the N NFC cards. Because all NFC cards in the security chip are activated, the first target NFC card corresponding to the transaction can be determined according to the verification requests sent by different second electronic devices, and therefore convenience can be brought to card swiping transactions of the first electronic device with a plurality of NFC cards.
Optionally, the determining, based on the first non-connection parameters, a second non-connection parameter corresponding to each NFC card includes:
Acquiring a first non-connection parameter of at least one second target NFC card in the N NFC cards, wherein the first non-connection parameter of the second target NFC card comprises an identity of the second target NFC card;
And adding a second non-connection parameter corresponding to the second target NFC card in the NFC chip based on the identity of the second target NFC card.
The N NFC cards comprise second target NFC cards, and the second target NFC cards are NFC cards which are stored in the security chip and correspond to the first non-connection parameters. Based on the identity of the second target NFC card, when the corresponding second non-connection parameter of the second target NFC card is not already stored in the NFC chip, the second non-connection parameter corresponding to the second target NFC card may be added to the NFC chip.
The method comprises the steps of obtaining a first non-connection parameter corresponding to a second target NFC card in a security chip, wherein the first non-connection parameter comprises an identity mark of the second target NFC card, further, sending the identity mark of the second target NFC card to the NFC chip, comparing whether the identity mark in the received first non-connection parameter is recorded or not by the NFC chip, and further, if the identity mark is not recorded, indicating that the NFC chip does not store the second non-connection parameter corresponding to the second target NFC card yet, adding the second non-connection parameter corresponding to the second target NFC card into the NFC chip.
In this embodiment, a first non-connection parameter of at least one second target NFC card of the N NFC cards is obtained, where the first non-connection parameter of the second target NFC card includes an identity of the second target NFC card, and further, based on the identity of the second target NFC card, a second non-connection parameter corresponding to the second target NFC card is added to the NFC chip. Under the condition that the NFC chip does not store the second non-connection parameters corresponding to the second target NFC card, the second non-connection parameters corresponding to the second target NFC card can be added in the NFC chip, so that the NFC chip can store the second non-connection parameters corresponding to the plurality of NFC cards, and convenience can be brought to card swiping transactions of the first electronic device with the plurality of NFC cards.
Optionally, before storing the second non-connection parameters in the corresponding NFC chip, the NFC chip stores a third non-connection parameter of a third target NFC card, and adding, in the NFC chip, the second non-connection parameters corresponding to the second target NFC card includes:
And adding a second non-connection parameter corresponding to the second target NFC card in the NFC chip, and updating a third non-connection parameter of the third target NFC card to the second non-connection parameter corresponding to the third target NFC card.
The third target NFC card is a card of a third non-connection parameter corresponding to a third target NFC card stored in the NFC chip before the second non-connection parameter corresponding to the third target NFC card is stored in the NFC chip. Generally speaking, according to different transaction requirements, the non-connection parameters of the NFC card may be changed, and when the first non-connection parameters corresponding to the third target NFC card in the secure chip are changed, the corresponding second non-connection parameters corresponding to the third target NFC card in the NFC chip also need to be changed.
Before the second non-connection parameters are stored in the corresponding NFC chip, under the condition that the third non-connection parameters of the third target NFC card are stored in the NFC chip, the second non-connection parameters corresponding to the second target NFC are added in the NFC chip in a mode that firstly, according to the first non-connection parameters of the third target NFC card in the security chip, the NFC chip receives the second non-connection parameters corresponding to the third target NFC card and the first non-connection parameters, and further, in the NFC chip, the stored third non-connection parameters of the third target NFC card are updated to the second non-connection parameters corresponding to the third target NFC card, so that the non-connection parameters of the third target NFC card in the NFC chip and the first non-connection parameters of the third target NFC card in the security chip can be synchronized.
In this embodiment, by adding the second non-connection parameter corresponding to the second target NFC in the NFC chip and updating the third non-connection parameter of the third target NFC card to the second non-connection parameter corresponding to the third target NFC card, the existing non-connection parameter corresponding to the third target NFC card may be updated in the NFC chip, so as to meet the requirements of different transactions.
Optionally, after determining a second non-connection parameter corresponding to each NFC card based on the first non-connection parameter, and storing the second non-connection parameter in the NFC chip, the method further includes:
Determining a default non-access parameter in the second non-access parameters, wherein the default non-access parameter is related to at least one of the use frequency of the NFC card, the use time of the NFC card and a key corresponding to the NFC card;
and determining the first target NFC card in the N NFC cards according to the default non-connection parameters.
After the second non-connection parameters are stored in the NFC chip, the NFC chip can set the second non-connection parameters of a certain NFC card to default non-connection parameters according to a preset strategy, meanwhile, the NFC card corresponding to the default non-connection parameters can be determined to be a first target NFC card used for transaction, and when the transaction is carried out, the first target NFC card can be used for carrying out the transaction by default.
The preset policy may be set by a user or may be determined by the system, where the preset policy mainly includes setting a second non-connection parameter of an NFC card with a highest frequency of use as a default non-connection parameter, setting a second non-connection parameter of an NFC card with a longest use time as a default non-connection parameter, and setting a second non-connection parameter of an NFC card corresponding to a last stored card key as a default non-connection parameter. As such, the determination of the default non-access parameters is related to at least one of a frequency of use of the NFC card, a time of use of the NFC card, and a key corresponding to the NFC card. Therefore, the user is not required to provide privacy information such as geographic positioning information and the like to judge the use scene of the NFC card, and the collection of the privacy information of the user is avoided to determine the first target NFC card for transaction.
In this embodiment, after storing the second non-connection parameters in the NFC chip, determining a default non-connection parameter of the second non-connection parameters, where the default non-connection parameter is related to at least one of a frequency of use of the NFC card, a time of use of the NFC card, and a key corresponding to the NFC card, and further determining, according to the default non-connection parameter, the NFC card corresponding to the default non-connection parameter as the first target NFC card for the transaction. According to the use condition of the NFC card by the user, the default non-connection parameters in the second non-connection parameters can be determined, so that the first target NFC card for transaction is determined to be related to the use condition of the user, and the experience effect of the user on using the NFC card can be improved.
In a specific embodiment, the first electronic device is an intelligent terminal, the second electronic device is a POS machine, and determining that the first target NFC card is used for card swiping transaction in the plurality of NFC cards mainly includes four steps of storing respective non-connection parameters of the plurality of NFC cards in the security chip, activating the plurality of NFC cards in the security chip, storing respective non-connection parameters of the plurality of NFC cards in the NFC chip, determining the first target NFC card for transaction, and performing card swiping transaction.
As shown in fig. 3, the process of storing non-connection parameters corresponding to each of the plurality of NFC cards in the security chip and activating the plurality of NFC cards in the security chip mainly includes:
Step 301, opening the card. The NFC card is turned on, and is referred to herein and hereinafter simply as a card. Generally, when a user opens a card, operations such as downloading an application, installing an application, setting non-access parameters, and personalizing the card need to be performed.
Step 302, whether all cards are activated simultaneously. The user may choose whether to activate all cards in the security chip at the same time, in case the user chooses to activate all cards at the same time, step 303 is performed, and in case the user does not choose to activate all cards at the same time, step 307 is performed.
Step 303, modify the instruction to set the non-receiving parameter to the security chip, and modify the priority to "0". By modifying the priority to "0", the security chip can activate multiple cards simultaneously.
Step 304, an instruction for storing a plurality of non-connection parameters is sent to the NFC chip. The updated NFC chip may store a plurality of non-access parameters according to the instruction.
Step 305, whether a default card needs to be set. According to any one default card setting strategy of the using frequency of the NFC card, the using time of the NFC card and the secret key corresponding to the NFC card, one card meeting the preset strategy requirement in the plurality of cards can be set as the default card for transaction. Step 306 is performed in case the default card needs to be set, and the flow is ended in case the default card does not need to be set.
Step 306, sending an instruction for setting a default card to the NFC chip. The NFC chip receiving the instruction may set the contactless parameter of the default card as a valid parameter for the transaction. The flow is ended.
Step 307, executing according to the original instruction. In the case of execution as original instructions, the security chip cannot activate all cards at the same time due to priority conflicts of non-access parameters.
Step 308, whether a default card needs to be set. Under the condition that all cards cannot be activated simultaneously by the security chip, one card meeting the preset strategy requirement in the plurality of cards can be set as a default card for transaction according to any one strategy of the using frequency of the NFC card, the using time of the NFC card and the secret key corresponding to the NFC card. In the case where the default card needs to be set, step 309 is executed, and in the case where the default card does not need to be set, the flow is ended.
Step 309, sending an instruction for setting a default card to the NFC chip. The NFC chip receiving the instruction may set the contactless parameter of the default card as a valid parameter for the transaction. The flow is ended.
As shown in fig. 4, the process of storing the non-connection parameters corresponding to each of the plurality of NFC in the NFC chip includes:
Step 401, activating cards, activating all cards in the security chip,
Step 402, CRS determines whether the non-access parameters conflict. If the priorities of all the cards are 0, the corresponding non-connection parameters cannot conflict, and if the priorities of two or more cards are F, the corresponding non-connection parameters can conflict. Step 403 is performed if there is no conflict in the non-connection parameters, and step 405 is performed if there is a conflict in the non-connection parameters.
Step 403, the security chip activates the card. In the event that there is no conflict in the non-access parameters, all cards in the security chip are activated.
Step 404, notifying the NFC chip to update or store the non-connection parameters, and setting the card as a default card in the NFC chip. When the NFC chip does not store the non-connection parameters of the card, the non-connection parameters of the card are stored in the NFC chip, the corresponding non-connection parameters are stored for the NFC chip, and when the non-connection parameters of the card are stored in the NFC chip, the non-connection parameters of the card in the NFC chip are updated. The flow is ended.
Step 405, reject the activation instruction. And if the CRS judges that the conflict exists among the non-access parameters, the activation of all cards is refused. The flow is ended.
As shown in fig. 5, the process of storing non-connection parameters corresponding to each of the plurality of NFC cards in the NFC chip includes:
Step 501, modify the storage logic of the NFC chip, and support more instructions, so that it can store multiple sets of non-connection parameters at the same time. The current NFC chip can only store the non-connection parameters of one card, so that the NFC needs to be upgraded so that it can store the non-connection parameters of a plurality of cards.
Step 502, whether to store a plurality of non-connection parameters. After the NFC chip is upgraded, a user can select to store non-connection parameters of a plurality of cards, and can also select to not store the non-connection parameters of the plurality of cards. Step 503 is performed when a plurality of non-connected parameters are stored, and step 504 is performed when a plurality of non-connected parameters are not stored.
Step 503, storing non-connection parameters of a plurality of cards, and setting the non-connection parameters of a certain card as default parameters according to a certain strategy. Policies include, but are not limited to, the last stored key, cards that were frequently used by the user, cards that were last used by the user, and so forth. The flow is ended.
Step 504, the non-connection parameters of other cards are cleared, and only the non-connection parameters of the card are stored. In the case where the user selects not to store the non-connection parameters of a plurality of cards, only the non-connection parameters of one card are stored. The flow is ended.
As shown in fig. 6, the process of determining a first target NFC card for a transaction and performing a swipe transaction mainly includes:
step 601, the POS machine sends an instruction to the intelligent terminal. When the card swiping transaction is required, the instruction sent by the POS machine to the intelligent terminal can be regarded as a verification request.
And 602, the intelligent terminal returns information according to the currently set non-connection parameters.
Step 603, the POS machine verifies whether the returned information is correct. Step 604 is performed if the POS verification returned information is incorrect, and step 605 is performed if the POS verification returned information is correct.
And step 604, the intelligent terminal closes the card simulation function, switches the default card of the NFC chip to other cards, and opens the card simulation.
Step 605, the POS machine sends an instruction for selecting the card. According to the instruction, the non-connection parameters corresponding to the transaction in the NFC chip can be confirmed.
Step 606, the intelligent terminal analyzes whether the card expected by the POS machine is consistent with the default card set by the current NFC chip from the card selecting instruction. Step 607 is performed if the card desired by the POS machine is consistent with the default card set by the current NFC chip, and step 608 is performed if the card desired by the POS machine is consistent with the default card set by the current NFC chip.
