Radio-frequency identification mark and related deterministic device and method, and management system and method

Abstract

The present invention provides an RFID (Radio Frequency Identification) tag structure suitable for determining the authenticity of goods or parts, and also provides an information processing system for reading RFID tags that can accurately perform read-only RFID tags Authenticity determination of goods or components. A plurality of RFID tags are designed to have a service identifier and service data as tag information, each RFID tag holds tag information in a ROM (Read Only Memory), and responds to tag information via radio waves upon receiving radio waves from a reader, The service identifier designates a common utilization target with the same value, and the service data sets different values ​​for each RFID tag. Then, by dividing the data structure of an RFID tag with a read-only memory into a service identifier and serial data, it is possible to confirm that the commodity is genuine by simply confirming the service identifier, which is common to a certain commodity, and the serial Data is used to manage individual products.

Description

technical field [0001] The present invention relates to a data structure of an RFID (Radio Frequency Identification) tag using a non-contact IC chip, an information processing system for reading the RFID tag, and a product authenticity determination system for determining the authenticity of a product using the RFID tag . Background technique [0002] Traditional RFID tags usually have read and write memory. Reading and writing memory is conducive to freely rewriting the contents of the memory, but it is possible to produce counterfeit RFID tags if it can be rewritten. Various techniques have been practiced to prevent counterfeiting. For example, for banknotes, microprinting, watermarking and other specialized manufacturing techniques indicate that the banknote is genuine, and in credit cards, holography is used to prevent counterfeiting. [0003] When RFID tags are used to prevent counterfeiting and the like, RFID tags having read and write memories (hereinafter referred...

AI Technical Summary

Problems solved by technology

However, the problem with reading and writing RFID tags is that the chip size is large and the price is high since a dedicated circuit for rewriting the memory and a safety circuit for preventing free rewriting of the memory are required

[0004] And since it's impossible to prevent counterfeit markings in the past, it's impossible to accurately determine authenticity without a system in place to determine authenticity
