Problems solved by technology
To sum up, magnetic effect technology is easy to use, but easy to crack; anti-counterfeiting ink and laser hologram technology, inconvenient to use, and easy to crack; miniature printing technology, inconvenient to use, moderately difficult to crack; biotechnology, microchip technology And isotope technology, difficult to crack, but inconvenient to use, and the cost is too high
The application defect of existing anti-counterfeiting technology other than banknotes is that it cannot be identified by equipment, consumers cannot recognize it, and the due role of anti-counterfeiting technology has not been played

The invention relates to a recognition terminal of tickets in an antiferromagnetic resonance material. The terminal comprises a control unit, a modulation circuit, a power amplification circuit, a frequency generation circuit, a demodulation circuit, a signal amplification circuit, and a radio frequency antenna circuit. Compared with the prior art, the terminal has the following advantages: (1) an antiferromagnetic resonance radio frequency identification technology realizes perfect combination of anti-fake material, digital signal, and instrument identification, and is not security in a single method; (2) the antiferromagnetic resonance radio frequency identification material cannot be simulated; (3) signal extraction has diversity, the antiferromagnetic resonance effect of a plurality of components is extracted, a plurality of parameters of an antiferromagnetic resonance radio frequency identification characteristic curve are selected, and signal processing is safe and flexible; (4) information reading is flexible and information can be converted; (5) after accidents occur, a system is rapidly recovered and a scheme is rapidly recovered, same tags and the system are used continuously, and a recognizer is adjusted, after calibration, the recognizer can read more antiferromagnetic resonance radio frequency identification signals, speed is fast, and cost is very low.
Description
[0001] This application is a divisional application of the following application, application date: October 28, 2013, application number: 201310516322.7, invention name: antiferromagnetic resonance radio frequency identification ticket management terminal. technical field [0002] The invention relates to ticket inspection and security anti-counterfeiting technology, in particular to a barcode reading control method for an identification terminal of an antiferromagnetic resonance material ticket. Background technique [0003] All kinds of tickets (such as invoices, checks, graduation certificates, degree certificates, driver's licenses, tickets, train tickets, etc.), counterfeit emerge in endlessly, causing extremely serious economic, political, legal, moral and other problems to the society. Fake invoices are typical examples . False invoices have harmful behaviors such as disrupting market order, affecting fair competition, leading to tax loss, interfering with tax collect...
