An easy-to-tear high-frequency RFID anti-counterfeit label and its manufacturing method

Abstract

The invention discloses an easy-to-tear ultrahigh-frequency RFID (radio frequency identification) anti-counterfeit tag and a production method thereof. The RFID label comprises a panel material (1), an electric chip layer (3), an antenna inductive circuit layer (4), an antenna thin film base material (6), an antenna capacitive circuit layer (8) and a bottom paper layer (10). One surface of the panel material (1) splices on one surface of the electric chip layer (3), the other surface of the electric chip layer (3) recombines with one surface of the antenna inductive circuit layer (4), the other surface of the antenna circuit layer (4) splices on one surface of the antenna thin film base material (6), the other surface of the antenna thin film base material (6) splices on the antenna capacitive circuit layer (8), and the other surface of the antenna capacitive circuit layer (8) spices on the bottom paper layer (10); the antenna inductive circuit layer (4) is electrically connected with the antenna capacitive circuit layer (8). The easy-to-tear ultrahigh-frequency RFID anti-counterfeit tag has wide application prospect in the fields of liquor traceability, tobacco verification, file encryption, ticket security, electric appliance security, smart gasmeters, smart electric meters, logistics inspection and the like.

Description

technical field [0001] The invention belongs to the technical field of the Internet of Things, and also belongs to the field of anti-counterfeiting technology, and in particular relates to an easy-to-tear high-frequency RFID anti-counterfeiting label and a manufacturing method thereof. Background technique [0002] Radio frequency identification technology uses radio frequency identification signals to identify objects. Radio frequency identification technology is a technology with a built-in radio chip, which can store a series of information. Generally, an RFID system consists of three main parts: electronic tags, readers and data management systems. [0003] RFID is widely used in logistics, retail, manufacturing, clothing, medical, identification, anti-counterfeiting, asset management, transportation, food, animal identification, library, automobile, aviation, military and other fields. [0004] The electronic tag consists of an antenna and an RFID chip, and each chip ...

Problems solved by technology

The disadvantage is high cost and slow production speed

[0006] 2. Laser direct writing process: only a small amount of proofing can be made, which cannot meet mass production

[0008] 4. Screen printing process: the advantage is high selectivity to the substrate; however, conductive silver paste is usually used, which has high cost and limited conductivity

[0010] 6. Die-cutting process: The requirements for die-cutting mechanical wear and precision control are relatively high, and it is still in the research and development stage

[0012] Chinese Patent No. 201220312800.3 discloses a RFID high-frequency fragile anti-counterfeiting antenna. Although the patented product has its advantages, it adopts a groove structure or a sawtooth structure by cutting the edge of the antenna base material PET to achieve a fragile function. This method is very It is difficult to mass produce, and it will also affect the appearance of the antenna label
