Embodiment Construction

[0038] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention.

[0039] like Figure 1 to Figure 3 As shown, a card issuing method for RFID tags includes the following steps: Step A. Write a batch of initial electronic product codes (Electronic Product Code Identity, EPC ID) written according to rules into a storage area. Step B, read the tag identifier (Tag Identity, TID) of the RFID tag, respectively encrypting each code in the batch initial electronic product code and a corresponding tag identifier by an encryption method to generate a new electronic product code , the tag identifier of the RFID tag is globally unique. Step C. Write new electronic ...

Abstract

The present invention is applicable to RFID technology, and provides a card issuing method of RFID tags and a card issuing device. The card issuing method of RFID tags includes the following steps: Step A, writing the batches of initial electronic product codes written according to the rules into the storage area ; Step B, read the tag identifier of the RFID tag, generate a new electronic product code after each code in the initial electronic product code of the batch and a corresponding tag identifier are encrypted by an encryption method, and the RFID tag The tag identifier has global uniqueness; step C, write the new electronic product code into the RFID tag in batches. The card issuing method of the RFID tag can write batches of electronic product codes into the RFID tag, and encrypt the RFID tag. After encryption, the uniqueness of the data can be determined, and it can prevent others from illegally copying, stealing and Rewrite etc.

Description

technical field [0001] The invention relates to radio frequency identification technology, in particular to a card issuing method and a card issuing device of an RFID tag. Background technique [0002] RFID (Radio Frequency Identification, radio frequency identification) tags are currently widely used cards with chips. Because each tag has the unique Tag Identity (tag identifier) ​​in the world, storage area, multi-level locking with available password, non-contact reading and writing, and has the characteristics and advantages of thin volume, light weight, easy processing, etc., it is widely used. in various solutions. [0003] When the user writes the RFID tag, he usually writes the EPC ID (Electronic Product Code Identity, electronic product code) according to his own rules and writes it into the storage area, and then locks the RFID tag at the corresponding level to prevent it from being blocked. Malicious modification. However, after the existing RFID tags are locked...
