[0096] Such as figure 2 As shown, it is a specific flowchart of a synchronous data processing method for scanning terminal communication of the present invention, including the following steps:
[0097] S1: Define the TLCV data format for synchronous data processing, the TLCV data format is specifically:
[0098] T: represents a TAG tag, including a unique identification code TAG and an application TAG, wherein the unique identification code TAG is used to solidify the solidified information in the communication request including the device sn number, operator ID, and operator name, including 8 A fixed item of 1 byte and a version number of 2 bytes; the application TAG is used to mark the data information in the communication request, including order number, discount offer, bill, and commodity information, including 1 byte of data number and a 2-byte version number.
[0099] L: Represents the length of LENGTH, represented by a 2-byte hexadecimal number, used to count the le...

[0131] This embodiment is an embodiment of practical application with specific data corresponding to the first embodiment, and is only used to explain the present invention, not to limit the present invention, as follows:
[0132] Before data communication, it is first necessary to divide a part of the application TAG for storing fixed information TAG, for example: 0x09 (order number), 0x0A (discount discount), 0x0B (whole order discount), 0x0C (bill), 0x 0E (add product information), 0x0F (number of products), 0x01 (userID), 0x02 (SN), 0x03 (userName), etc. 0xA0-0xFF are used to represent the commodity information TAG, and a table corresponding to the barcode of the commodity information and the application TAG is maintained in the database corresponding to the back-end device for management. At the same time, the above table is dynamically maintained. Each application TAG does not always correspond to a barcode of product information. According to the current usage, the barc...
