The following terms and definitions apply to this document. 3.1
Intelligent traceability scale is an electronic scale that integrates weighing, contactless IC card reading and writing, voucher printing and other functions, and can receive and transmit relevant information through wired or wireless methods. At the same time, the weighing instrument (terminal) can be connected to a printer to print traceability tickets. 3.2
Intelligent reader and writer terminal is a mobile or fixed device that has functions such as barcode reading, RFI and IC card reading and writing, handwriting input, etc. and can transmit information through wireless or wired methods.
Radio frequency identification
Radio frequency identification is a contactless motion identification technology. It can automatically identify the target object and obtain relevant data through radio frequency signals. It can identify high-speed moving objects and can identify multiple tags at the same time. It is quick and convenient to operate. 1

Note: This standard includes card writing at the wholesale and retail links. *The mark indicates that the content of the block can be converted into an integer in hexadecimal to save space. REC represents the transaction number 1. Two digits are reserved for the brand code, which can be defined by each city. If not needed, it can be defaulted to \00". The transaction quantity, transaction weight, and transaction amount are all stored in numbers. The transaction quantity of live pigs may be 0.5 heads. In this case, it is generally converted into an integer and stored as 0.5×10. The maximum transaction quantity for each transaction is 429496729.5 heads; similarly, the transaction amount is stored with 2 digits after the decimal point. , can be multiplied by 100 and then converted into an integer for storage. The traceability code is 20 digits long. Since it is all numbers, but the maximum supported by the 8-byte long integer is 18446744073709551615, the number of digits may not be sufficient. Consider splitting the traceability code into two parts, namely 18-1-2, that is, the first 18 digits plus the last 2 digits. In this way, only 8 bytes plus 1 byte, a total of 9 bytes, are needed for storage. Every three sectors are stored as a transaction record in a loop, and finally a sector is reserved for expansion. 4. 2.2 CPU card writing standard

Length (character book)
User transaction information is divided into two parts, of which the first part is transaction statistics information, with a length set to 20 bytes, including transaction date (8 bytes, format YYYYMMIDD), transaction number (2 bytes, stored in integer), transaction type (1 byte) transaction market principal code (4 bytes) Table 5 Transaction statistics

For example, vegetables: 1 represents the origin of the product, 2 represents the upstream wholesale farm
For meat: 1 represents wholesale, 2 represents retail Length (section)
The second part is the transaction details data, which is a cyclic content, with a length of 10,000 bytes, and each record length is 200 bytes. If the number of digits is insufficient, add spaces, and a total of 50 records can be written. Table 6 Transaction details data
Tracing code
Batch code
For each transaction, follow the & coding rules to write the traceability code. No matter meat or vegetables, no new tracking code is generated in the retail stage, and the tracking code generated during the last wholesale is used. The batch code is established for the first batch of vegetables.The code used to distinguish batches when recording accounts shall be implemented in accordance with the rules of the Coding Regulations. For meat, the batches shall be distinguished by the quarantine certificate number of the origin of pigs or the quarantine certificate number of meat products. Length (bytes)
