Disposable RFID electronic anti-counterfeit tag structure

Abstract

The invention relates to the technical field of electronic tags, and discloses a disposable RFID electronic anti-counterfeit tag structure which comprises a base, the bottom of the inner wall of the base is fixedly connected with the outer side wall of a bottom plate, the top of the bottom plate is fixedly connected with the bottom of a tag antenna and the bottom of a tag chip, and the tag chip islocated on the inner side of the tag antenna. A tag antenna and the tag chip are fixedly connected with one ends of the two groups of copper wires respectively. According to the disposable RFID electronic anti-counterfeit tag structure, a white phosphorus sheet and a low-melting-point connecting wire are arranged, after shielding of the white phosphorus sheet is canceled, the white phosphorus sheet makes contact with air, the white phosphorus sheet generates an oxidation reaction, the white phosphorus sheet generates heat in the oxidation reaction process, and heat is transmitted to the connecting wire by a heating hole. Thus, the low-melting-point connecting line is fused, connection between the tag chip and the tag antenna is canceled, and the electronic tag cannot be scanned and used again.

Description

technical field [0001] The invention relates to the technical field of electronic labels, in particular to a disposable RFID electronic anti-counterfeit label structure. Background technique [0002] Electronic tags are also called radio frequency tags, transponders, and data carriers; readers are also called readout devices, scanners, reading heads, communicators, and readers (depending on whether the electronic tags can rewrite data wirelessly). The space (non-contact) coupling of radio frequency signals is realized through the coupling element between the electronic tag and the reader; in the coupling channel, energy transmission and data exchange are realized according to the timing relationship. Electronic tags have the following characteristics: Data storage: Compared with traditional tags, the capacity is larger (1bit-1024bit), data can be updated at any time, and can be read and written; Faster reading and writing speed, multi-target recognition and motion recogniti...

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a disposable RFID electronic anti-counterfeiting label structure, which has the advantages of one-time use of the electronic label and the ability to destroy the connection at the physical level, which improves the safety of product use and solves the problem of The vast majority of electronic tags do not have the function of one-time use, and a small number of one-time tags are also rewritten at the software level to achieve the purpose of one-time use, which is easier to be cracked
