A compatible data format used by active RFID

Abstract

The invention provides a compatible data format used for an active RFID (radio frequency identification device). By the compatible data format used for the active RFID, bottlenecks can be eliminated, and the existing mainstream RFID reading data format is compatible. The compatible data format comprises a format version number, an RFID name and model code, an RFID command format block, an RFID data grouping block, a standby auxiliary block, a data encrypting and decrypting block and an end mark block, wherein the format version number has 3 bytes; the RFID number and model code has 40 bytes; the RFID command format block has 1024 bytes; the RFID data grouping block has 4096 bytes; the standby auxiliary block has 1024 bytes; the data encrypting and decrypting block has 512 bytes; and the end mark block has 10 bytes.

Description

technical field [0001] The present invention relates to data formats for RFIDs used in logistics, and more particularly, to a compatible data format for use in active RFIDs. Background technique [0002] At present, there is no formal international standard for RFID products (including various frequency bands). There are two coding systems for the application of RFID in logistics: one is the UID coding system proposed by the Japanese UID Center (Ubiquitous ID—Ubiquitous ID Center, which is actually the standardization organization for electronic tags in Japan), which supports this There are Japanese electronics manufacturers, information companies and printing companies in the camp, with a total of 352 companies. Another camp is the EPC electronic product coding standard proposed by the "EPC (Electronic Product Code) Global Association" of the United States. More than 100 distribution companies in the United States and Europe, such as the world's largest retailer Wal-Mart ...

Problems solved by technology

[0006] In the prior art, the Chinese invention patent application with the application number CN200810111908 tries to solve this problem, however, it ignores the problems of reading omission and reading repetition that are easy to occur in the RFID communication process, thus resulting in the inability to read through this protocol. Accurately and truly reflect the quantity and information of the actual logistics goods

In addition, it does not address the security issues of the data format
