Electromagnetic forgery prevention application of printing simulation radio frequency tag under standard printing process

Abstract

The invention provides an electromagnetic forgery prevention application of a printing simulation radio frequency tag under a standard printing process. The application is as follows: firstly manufacturing a printing simulation radio frequency tag; then reading a corresponding code by virtue of a reader; designing ten types of printing simulation circuits for a printing simulation radio frequency tag circuit under a given microwave radiation condition, wherein each circuit is corresponding to one number among ten numbers from 0 to 9; electromagnetic characteristics of each circuit include main resonance centre frequency characteristics and secondary resonant frequency phase characteristics. An encoding method for the electromagnetic response characteristics of each circuit is as follows: when a centre frequency value under a main resonance response modal is corresponding to numbers from 0 to 9, performing binary encoding on frequency-phase positive and negative values under a secondary resonance response modal. The printing simulation radio frequency tag can be printed on money and tickets by virtue of the standard printing process, so that the forgery prevention functional and a function of continuously and rapidly reading codes can be realized, and the design and online rapid detection requirements of a digital system based on money and ticket forgery prevention can be met.

Description

technical field [0001] The present invention relates to the field of anti-counterfeiting methods and detection technologies, in particular to an electromagnetic anti-counterfeiting application for printing simulated radio frequency tags under a standard printing process, specifically a banknote anti-counterfeiting and anti-counterfeiting technology based on the electromagnetic characteristics of a chipless radio frequency identification tag analog circuit and coding technology Too many devices. Background technique [0002] Since the reform and opening up, anti-counterfeiting technology has made great progress in the field of security printing in my country, and banknotes, stamps, passports, visas, electronic tickets, anti-counterfeiting marks, anti-counterfeiting tickets, securities, important bank certificates and anti-counterfeiting seals have been widely used in this country. fields are widely used. With the advancement of science and technology and the development of th...

Problems solved by technology

At present, the printability of magnetic ink is good, but it is difficult to quantitatively detect the distribution of a small amount of printed magnetic ink, which affects its anti-counterfeiting performance; while the latter is implanted with a wireless radio frequency identification chip, which cannot be used for banknotes under standard printing conditions. bill printing process; for this reason, a banknote anti-counterfeiting method and a system for realizing the method need to be produced urgently
