detailed description

In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

The present invention proposes a transaction information transmission method, referring to Fig. 1, the method mainly includes the following steps:

Step 101: The handheld terminal and the server of the cash register system establish a wireless connection through searching and matching.

The transaction information refers to the information related to the transaction behavior between the user and the merchant, including electronic documents and real-time scanned commodity information, and other data information related to the current transaction. For example, when shopping in a supermarket, the transaction information includes commodity information and electronic receipts. The commodity information is entered in advance by the cash register system and stored in the database. The electronic receipts are generated by the cash register system server after scanning all the commodities this time.

User handheld terminals are all portable handheld terminals with wireless sending and receiving functions, including mobile phones, Ipad, MP3, MP4, MP5, etc.

The wireless connection can be Bluetooth, wifi (wirelessfidelity, wireless fidelity), 3G (3rd-generation, third-generation mobile communication technology), WLAN (WirelessLocalAreaNetworks, wireless local area network), zigbee (Zigbee), CDMA (CodeDivisionMultipleAccess , Code Division Multiple Access), GSM (globalsystemformobilecommunications, Global System for Mobile Communications), TD-SCDMA (TimeDivision-SynchronousCodeDivisionMultipleAccess, Time Division Synchronous Code Division Multiple Access) and other formats. According to the transmission distance, it can be divided into short-distance transmission mode and long-distance transmission mode.

The specific process of establishing a wireless connection is as follows:

The name and address information of the wireless devices corresponding to more than one cash register system server are pre-recorded in the handheld terminal.

Then the handheld terminal searches for wireless devices, and obtains name and address information of wireless devices within the search range. For the short-distance transmission method, when the user is ready to check out, the wireless device of the handheld terminal should be turned on. For the long-distance transmission method, the cash register system server should send the electronic receipt to the handheld terminal after the user’s handheld terminal is turned on. , or send it offline.

The handheld terminal judges whether the name and address information of the searched wireless device match the wireless device name and address information corresponding to more than one cash register system server recorded in advance. If yes, enter the follow-up process; to a matching wireless device.

The matched wireless devices are listed in descending order of signal strength.

Judging whether the signal strength difference between the wireless device with the highest signal strength and the wireless device with the second signal strength exceeds a preset threshold, if yes, then use the wireless device with the highest signal strength as the connection object; if not, the handheld terminal pops up a user interface Perform manual confirmation of the wireless device, and use the wireless device selected by the user as the connection object.

The handheld terminal sends a connection confirmation message to the wireless device as the connection object, so as to realize the connection.

The hand-held terminal and the server of the cash register system perform search and matching, and the purpose is to send transaction information such as electronic receipts currently settled by the cash register system to the corresponding user's hand-held terminal. Different wireless transmission methods have different specific operation details of search and matching. Those skilled in the art can comprehend the essence of the technical solution of the present invention, and implement the specific steps of searching and matching according to the transmission characteristics of different wireless communication modes, which will not be repeated here.

Step 102: After the server of the cash register system confirms that the scanning of the commodities for this transaction is completed, it generates an electronic receipt for this transaction corresponding to the handheld terminal, and encapsulates the electronic receipt to restrict the handheld terminal from The authority of the above electronic documents is read-only.

The server side of the cash register system encapsulates the electronic documents, which is essentially an encryption process. The purpose is to make the user's authority to the electronic documents read-only and prevent malicious tampering and other acts.

As a possible implementation, in this embodiment, the encapsulation of the electronic document includes: adding header information in a fixed format to the electronic document, the header information includes the version number, the name of the unit to which the cash register system belongs, Transaction time, the name and address of the wireless device corresponding to the cash register system server, the wireless address and MD5 code corresponding to the handheld terminal.

The encryption process for encapsulating electronic documents is not limited to the above methods, and those skilled in the art can implement encryption steps of other schemes according to the technical idea of the present invention, which is not limited here.

In the second type of solution in the prior art, the merchant needs to hand over all the transaction information to a third party, which undoubtedly leaks the commercial information of the merchant and is unacceptable to many merchants. The technical solution of the present invention is to send the data corresponding to the user to the individual user, and encrypt it through encapsulation, and the user only has the right to read, which further protects the business information of the merchant.

Step 103: The cash register system server sends the electronic receipt corresponding to the handheld terminal to the handheld terminal in a wireless manner.

Step 104: The handheld terminal decapsulates the received electronic document.

It should be noted that when the wireless connection method is a long-distance transmission method, the existing wireless communication base station can be used as a transfer party, and the electronic bill can be sent to the cell server mentioned in the user's mobile terminal first, and then The community server sends the electronic documents to the user's handheld terminal. If the user's handheld terminal is a mobile phone, the electronic documents and other transaction information are first uploaded to the community server to which the user's mobile phone belongs, and then the community server sends the transaction information in SMS or MMS, etc. form, sent to the user's mobile phone. The transmission of transaction information can be realized by means of existing wireless communication networks such as China Mobile, China Telecom, and China Unicom.

In the prior art, users are required to enter their personal mailboxes every time they shop, and the operation is cumbersome. Both users and merchants are unwilling to accept the corresponding time cost, and users are unwilling to leave more personal information; and the technical solution of the present invention, There is no need for manual cumbersome operations, and it is mainly completed by the cash register system server and handheld terminals, which saves time and is more convenient and quick.

Referring to FIG. 2 , FIG. 2 is a flowchart of an embodiment of a transaction information transmission method of the present invention.

In this embodiment, the technical solution of the present invention is described in detail with Bluetooth as the wireless connection mode and supermarket shopping as the application scenario.

The present invention adopts the C/S (Client/Server, user machine/server) mode. In this embodiment, through Bluetooth transmission, while the cashier scans the commodity, the commodity information is displayed in real-time on handheld terminals such as the user's mobile phone with the Bluetooth function. After scanning, the Bluetooth device of the cash register system will package the electronic receipt, and send it to the user's handheld terminal after packaging.

The transaction information transmission method provided in this embodiment includes steps:

Step 201: The handheld terminal starts the bluetooth function.

Step 202: The handheld terminal searches for bluetooth devices, and obtains name and address information of bluetooth devices within the search range.

Step 203: The handheld terminal judges whether the name and address information of the searched Bluetooth device matches the Bluetooth device name and address information corresponding to more than one cash register system server recorded in advance, if yes, then enter step 204, otherwise, return to step 202 .

The name and address of the Bluetooth device at each supermarket cash register is pre-recorded in the software of the user's handheld terminal. After the function is turned on, the searched Bluetooth device is consistent with the pre-recorded information to achieve a match.

The search and match step is mainly to consider the uniqueness of the Bluetooth device connection. In order to avoid the risk of the Bluetooth device name and address information being fake or wrong, the judging link of whether the Bluetooth device name matches the Bluetooth address is designed.

Step 204: List the matched bluetooth devices in descending order of signal strength.

Step 205: Determine whether the signal strength difference between the Bluetooth device with the highest signal strength and the Bluetooth device with the second signal strength exceeds the preset threshold, if yes, then use the Bluetooth device with the highest signal strength as the connection object, and enter step 207, if not, then Go to step 206.

Most of the checkout counters in the supermarket are relatively close to each other. It is likely that the signal strengths sensed by the handheld terminal to the Bluetooth devices in the two nearby checkout counters are almost the same. In the actual measurement, there were two Bluetooth signals that were both significantly larger. , At this time, the handheld terminal cannot judge which device is the device to be connected to, so manual intervention is required to pop up the user interface, and the user manually selects the correct cash register channel.

The preset threshold is used to measure whether the signal strength difference between two adjacent Bluetooth devices is large enough. In this embodiment, RSSI (ReceivedSignalStrengthIndicator, received signal strength indicator) is used to characterize the Bluetooth signal strength, when Max( When RSSI(n))-Max(RSSI(n-1))>15, it is considered that it cannot be judged by itself. Those skilled in the art can adjust the size of the preset threshold according to the actual situation, which is not limited in the present invention.

Step 206: The handheld terminal pops up a user interface to manually confirm the Bluetooth device, and takes the Bluetooth device selected by the user as the connection object, and enters step 207;

The server of the cash register system is composed of Bluetooth devices in each channel of the supermarket to form a unified platform. In order to prevent the user's mobile phone and other handheld terminals from connecting to the Bluetooth "cross channel", manual channel confirmation is performed when automatic confirmation cannot be performed.

Step 207: The handheld terminal sends a connection confirmation message to the Bluetooth device as the connection object, so as to realize the connection.

Step 208: The cash register system server sends the commodity information corresponding to the handheld terminal scanned by the cashier to the handheld terminal in real time through wireless means.

Step 209: The handheld terminal displays the received commodity information.

In this way, the user's handheld terminal can display the detailed information of the goods scanned by the cashier in real time. In this embodiment, the handheld terminal is a portable terminal with a display function. Preferably, a mobile phone can be used, but other handheld terminals are not excluded.

The two technical solutions in the existing technology cannot perform real-time reconciliation for users like viewing traditional paper receipts. The viewing of transaction information is lagging behind the transaction behavior. If there is a problem in the transaction, it cannot be found on the spot. The user needs to find the merchant again for communication and negotiation, which is troublesome. In the technical solution of the present invention, the cash register system server sends the commodity information corresponding to the handheld terminal scanned by the cashier to the handheld terminal in real time through wireless means, and then the handheld terminal displays the received commodity information so that the user can receive it in real time. The transaction information is convenient for users to reconcile accounts in real time, find problems and question them on the spot.

Step 210: After the server of the cash register system confirms that the scanning of the commodities for this transaction is completed, it generates an electronic document for this transaction corresponding to the handheld terminal, and encapsulates the electronic document to restrict the handheld terminal from viewing the electronic document. The permission of the document is read-only.

Supermarket e-receipts are a type of documents that do not require high confidentiality. However, in order to prevent relevant personnel from using the same e-receipt to issue multiple invoices and other bad behaviors, users should have read-only access to the received e-receipt.

In this embodiment, the encryption setting is implemented by encapsulating the electronic receipt. The specific operation is to add a fixed-format demo version header information to the electronic receipt. The header information includes the version number, the name of the unit to which the cash register system belongs, the transaction time, the name of the Bluetooth device, the address of the Bluetooth device, and the handheld terminal. Bluetooth address and MD5 code.

As a possible implementation, the header information specifically includes: 1-byte version number + 20-byte supermarket name + 14-byte transaction time + 16-byte supermarket cash register channel Bluetooth name + 6-byte supermarket cash register channel Bluetooth address + 16 bytes Byte (empty, for writing other information) + 6 bytes user mobile phone Bluetooth address + 16 bytes MD5 code, the MD5 code is used to uniquely identify an electronic receipt, that is, an electronic receipt has a unique MD5 value.

The user's handheld terminal should not be designed with a UI (UserInterface, user interface) that can complete the modification operation, but the user may forcibly modify the electronic receipt by other means, so the MD5 code of the electronic receipt is included in the header information to prevent this. If the situation occurs, such as modifying the date to forge different electronic receipts for repeated invoices, etc., when the user’s handheld terminal reads the electronic receipts, it will first verify the MD5, and it will not pass and an error will be reported.

Step 211: The cashier system server sends the electronic receipt corresponding to the handheld terminal to the handheld terminal in a wireless manner.

Step 212: The handheld terminal decapsulates and displays the received electronic document.

Preferably, the handheld terminal can generate a secure personalized report for the user according to the electronic receipt.
