Each electronic tag has a globally unique ID number, which can be used to facilitate anti-counterfeiting, but the system needs to store and remember the ID number of each legitimate electronic tag. As the number of electronic tags used in the system becomes larger and larger, this method becomes quite cumbersome. For this reason, our company proposes to implement the secondary authorization of the reader for the manufacturer and the user, and to write the authorization code for the issue of electronic labels to achieve the flexible anti-counterfeiting of electronic labels.
