Concrete real way

The technical solutions in the embodiments of the present invention are clearly and completely described in the following with reference to the accompanying drawings in the embodiments of the present invention. It is a partial embodiment of the invention, and not all of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative efforts are within the 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 cash register system server establish a wireless connection by searching for a match.

The transaction information refers to information related to the transaction behavior of the user and the transaction, including electronic documents and real-time scanned product information, as well as other data information related to the current transaction. For example, when shopping in a supermarket, the transaction information includes product information and electronic coupons. The commodity information is previously entered by the cash register system and stored in the database. The electronic ticket is generated by the cash register system server after scanning all the products.

The user's handheld terminal is any portable handheld terminal with wireless transmitting and receiving functions, including 'mobile phones, ipads, MP3, MP4, M_P5, etc.

The wireless connection may be Bluetooth, wifi (wireless fidelity), 3G (3rd~generation, third generation mobile communication technology), WLAN (Wireless Local Area. Networks, zigbeei zigbee) , CDMA (Code Division Multiple Access (CDMA), GSM (global system for mobile communications), TD-SCDMA (Time Division-Synchronous Code Division Multiple Access, Time Division, Synchronous Code Division Multiple Access) ) · Multiple 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:

The name and address information of the wireless device corresponding to one or more cash register system servers are pre-recorded in the handheld terminal.

The handheld terminal then searches for the wireless device to obtain the name and address information of the wireless device within the search range. For the short-distance transmission mode, when the user prepares to settle the account, it should be ensured that the wireless device of the handheld terminal is in the open state. For the long-distance transmission mode, the cash register system server should send the electronic document to the handheld terminal after the user handheld terminal is turned on. , or use offline delivery.

The handheld terminal determines whether the name and address information of the searched wireless device matches the wireless device name and address information corresponding to one or more pre-recorded cash register system servers, and then proceeds to the subsequent process, otherwise, continues to search for the wireless device until the search To the equipped wireless device.

The matched wireless devices are listed in order of signal strength from large to small.

Determining whether the difference between the signal strength of the wireless device with the highest signal strength and the wireless device with the second signal strength exceeds a preset threshold; if yes, the wireless device with the highest signal strength is used as the connection target; otherwise, the handheld terminal pops up the user The interface performs manual confirmation of the wireless device, and the wireless device selected by the user is used as a connection object.

The handheld terminal transmits a confirmation connection message to the wireless device as the connection object to implement the connection.

The handheld terminal and the cash register system server perform search matching, and the purpose is to send transaction information such as electronic receipts currently settled by the cash register system to the corresponding user handheld terminal, and different wireless transmission modes, specific operations details of searching and matching are also different. The technical personnel can understand the essence of the technical solution of the present invention, and specifically implement the specific steps of the search matching according to the transmission characteristics of different wireless communication modes, and details are not described herein.

Step 102: After the cash register system server confirms that the scan of the transaction product is completed, an electronic document of the transaction corresponding to the handheld terminal is generated, and the electronic document is encapsulated to limit the handheld terminal The permissions of the electronic document are read-only.

The server of the cash register system encapsulates the electronic document, which is essentially an encryption process. The purpose is to make the user's permission on the electronic document read-only, and prevent malicious tampering and the like.

As an implementation manner, in the embodiment, the encapsulating the electronic document includes: adding a fixed format header information to the electronic document, where the header information includes a version number, a unit name of the cash register system, Transaction time, wireless device name and address corresponding to the cash register system server, wireless location corresponding to the handheld terminal Address and MD5.

The encryption process of encapsulating the electronic document is not limited to the above-mentioned manner, and those skilled in the art can implement the encryption step of other solutions according to the technical idea of the present invention, which is not limited herein.

In the second type of solution of the prior art, the merchant needs to hand over all the transaction information to the third party, which is undoubtedly a leakage of the business information of the merchant, which is unacceptable to many businesses. The technical solution of the present invention is to send data corresponding to the user to the individual user, and encrypt by encapsulation, and the user only has the reading right, thereby further protecting the business information of the merchant.

Step 103: The cash register system server wirelessly transmits the electronic document corresponding to the handheld terminal to the handheld terminal.

Step 04: The handheld terminal decapsulates the received electronic document.

It should be noted that, when the wireless connection mode is a long-distance transmission mode, the existing wireless communication base station may be used as a transit party, and the electronic document may be first sent to the cell server of the user's mobile terminal, and then The cell server sends the electronic document to the user's handheld terminal. If the user's handheld terminal is a mobile phone, the transaction information such as the electronic document is first uploaded to the cell server to which the user's mobile phone belongs, and then the cell server uses the transaction information as a short message or a multimedia message. The form is sent to the user's mobile phone. Transaction information can be transmitted by means of existing wireless communication networks such as mobile, telecommunications, and Unicom.

In the prior art, the user is required to input a personal mailbox every time of shopping, the operation is cumbersome, the user and the merchant are unwilling to accept the corresponding time cost, and the user is unwilling to leave more personal information; and the technical solution of the present invention, No need for manual cumbersome work, mainly by the cash register system server and handheld terminal, saving time, more convenient and faster. Referring to Fig. 2, Fig. 2 is a flow chart showing an embodiment of a transaction information transmitting method of the present invention.

In the embodiment, the technical solution of the present invention is specifically described by using Bluetooth as the wireless connection mode and using the shopping as the application scenario.

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

The transaction information transmission method provided by the implementation includes the steps of:

Step 201: The handheld terminal starts the Bluetooth function.

Step 202: The handheld terminal searches for the Bluetooth device to obtain the name and address of the Bluetooth device in the search range.

Step 203: The handheld terminal determines the name and address information of the searched Bluetooth device and the Bluetooth device name and location corresponding to one or more pre-recorded cash register system servers. If the address information matches, if yes, go to step 204, otherwise, go back to step 202. The Bluetooth device name address of each supermarket cash register is pre-recorded in the software of the user's handheld terminal. The Bluetooth device searched after the function is turned on is consistent with the pre-recorded information.

The search matching step mainly considers the uniqueness of the Bluetooth device connection. In order to avoid the risk of the Bluetooth device name and address information being spoofed or wrong, the judgment step of whether the Bluetooth device name matches the Bluetooth address is designed.

Step 204: List the matched basket devices according to the signal strength from large to small.

Step 205: determining whether the difference between the signal strength of the Bluetooth device with the highest signal strength and the Bluetooth device with the second signal strength exceeds a preset threshold. If yes, the Bluetooth device with the highest signal strength is used as the connection object, and the process proceeds to step 207, otherwise, Proceed to step 206.

Most of the cashiers in the supermarkets are close to each other. It is very likely that the signal intensity of the handheld devices in the nearby two cashiers is almost the same. In the actual measurement, there are two Bluetooths that are significantly larger. Signal, at this time, the handheld terminal cannot judge which device is the device that should establish the connection, then the manual interface 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 sufficiently large. In this embodiment, the RSSI (Received Signal Strength Indicator) is used to represent the Bluetooth signal strength. When Max( R si iii))-Max( RSSI (n 1)) >I 5, it is considered that it cannot be judged by itself. The size of the preset threshold can be adjusted by the skilled person in the field according to the actual situation, and the invention is not limited.

Step 206: The handheld terminal pops up the user interface for manual confirmation of the Bluetooth device, and the Bluetooth device selected by the user is used as the connection object, and proceeds to step 207;

The server of the cash register system is composed of Bluetooth devices of various channels of the supermarket. In order to prevent the Bluetooth connection of the handheld terminal such as the user's mobile phone, the manual channel confirmation cannot be performed automatically.

Step 207: The handheld terminal sends a confirmation connection message to the Bluetooth device as the connection object to implement 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 a wireless manner in real time.

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

In this way, the user's handheld terminal can display the details of the cashier's scanned merchandise in real time. In this embodiment, the handheld terminal is a portable terminal having a display function, and preferably, the mobile phone is optional, but other handheld terminals are not excluded.

The two technical solutions in the prior art can not perform real-time reconciliation for the user like viewing the traditional paper ticket. The viewing of the transaction information has a lag with respect to the transaction behavior. If there is a problem in the transaction, it cannot be found on the spot. It is more troublesome for the user to find the merchant to communicate and negotiate again. In the technical solution of the present invention, the cash register system server transmits the commodity information corresponding to the handheld terminal scanned by the cashier to the handheld terminal in a wireless manner, and then the handheld terminal displays the received commodity information. Shows that the user can receive the transaction information in real time, which is convenient for the user to reconcile in real time, find the problem, and question on the spot.
