Problems solved by technology

[0005] In addition, the RFID tags based on traditional polyester materials are difficult to be destroyed and are easy to be transferred and reused. Criminals can completely peel off the RFID tags on genuine products through certain physical and chemical means without destroying their physical properties. structure, the label can still be read, and if it is pasted on the counterfeit product, it will be difficult to distinguish it from the real product, and it will lose its significance as anti-counterfeiting and logistics management

Abstract

The invention discloses a radio frequency identification label and a manufacturing method of the radio frequency identification label. The label comprises a surface mark layer, an upper adhesion layer, a fragile radio frequency identification layer and a lower adhesion layer, wherein the layers are sequentially and mutually combined. The fragile radio frequency identification layer comprises a release layer, a radio frequency identification antenna, a chip, an isolating layer and a conducting layer, wherein the isolating layer is provided with a chip hole and a vertically through bridge hole, the antenna is arranged on one side of the isolating layer, the conducting layer is located on the other side of the isolating layer, the chip is arranged in the chip hole, the isolating layer is provided with small holes communicated with the chip hole and the bridge hole, the conducting layer penetrates through the bridge conducting hole to be connected with the antenna, and the chip adheres to the radio frequency identification antenna through a conductive adhesive. The label is good in anti-fake performance and free of the problem that conducting is influenced by material rebounding and the like, so that the rate of finished products is greatly increased, and product cost is reduced.

Description

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