Problems solved by technology

[0004] At present, most of the RFID tags on the market use paper or polyester film as the base material for production, especially the aluminum etching RFID tags that are widely used at present. In view of the limitations of its aluminum etching process and chip binding process, the prepared RFID tags It is tightly bonded to the substrate, which provides good processing and use stability, but it also limits its application in the field of commodity circulation, especially in the field of commodity anti-counterfeiting
Criminals can use certain physical and chemical means to completely peel off the RFID tag on the genuine product without destroying its physical structure, and the tag can still be read. If it is pasted on the counterfeit product, it will be difficult to distinguish it from the genuine product. Lost its significance as anti-counterfeiting and logistics management

Abstract

The present invention provides a radio frequency identification tag having a diversion-proof function and a manufacturing method thereof. The radio frequency identification tag having a diversion-proof function is formed of a support layer, a release layer, antennas and a chip; the release layer is attached to one side of the support layer, the antennas are attached to the other side of the release layer, or, the antennas are attached to two sides of the support layer and the release layer, and connected through overbridge points on the antennas, and the overbridge points run through the support layer and the release layer so that antennas at two sides are switched into conduction; and the chip is bonded onto the antennas. When the diversion-proof RFID tag is stripped or diverted, the physical structure thereof is damaged, information contained therein cannot be read, so as to achieve the purpose of being incapable of reuse. At the same time, a thermally curable resin is organically combined according to the fabrication process of the RFID tag, so that high bonding fastness is provided between the bonding point of the chip as well as the overbridge points and the support layer, it is uneasy for the chip to drop off due to the release layer, the overbridge effect is better, and the yield of the diversion-proof RFID tag may be greatly improved.

Description

technical field [0001] The invention relates to a radio frequency identification electronic tag and a preparation method thereof. Background technique [0002] Radio frequency identification (RFID for short) technology automatically identifies target objects and obtains relevant data through radio frequency signals. The identification work does not require manual interference and can work in various environments. It can identify multiple tags at the same time, and the operation is fast and convenient. After 2004, RFID technology has developed vigorously, and has wide application potential in the fields of warehousing and logistics, product anti-counterfeiting, product circulation, and product maintenance and tracking. In the application of product anti-counterfeiting, RFID is called a new generation of "electronic patron saint" because of its safety, efficiency, speed, large storage capacity, and free change of stored information. [0003] At the same time, because the UID ...
