The invention provides a use method of an RFID rubber cap with anti-counterfeiting and tampering detection functions. The rubber cap mainly consists of an RFID chip with a security algorithm and a matching coil. The RFID chip supports safety calculation and authentication functions, realizes one-object-one-code identity identification application, adopts a passive communication mode, and realizes bidirectional communication with NFC main control equipment in a high frequency band. According to the RFID tag, a chip and an antenna coil are bound together, the coil is divided into two parts, a main coil is connected with a chip radio frequency pin to achieve energy acquisition in an electromagnetic coupling mode, an auxiliary coil is connected with a chip tampering detection pin, after the auxiliary coil is broken due to unsealing of a commodity, the unsealed state can be recognized through scanning again, and the unsealing state is transmitted to the NFC main control equipment according to a related protocol. The anti-counterfeiting and tamper-proof rubber cap is attached to a sealing opening of a bottled commodity and is used for realizing the functions of identifying the identity of the commodity and detecting the unsealing of the commodity.
Description
technical field [0001] The invention relates to the technical field of radio frequency identification, in particular to a method for using an RFID rubber cap with anti-counterfeiting and tamper detection functions. Background technique [0002] Radio frequency identification technology (commonly known as electronic tags) has been increasingly used in anti-counterfeiting technology because it can adopt various encryption measures for the data in the chip. The anti-counterfeiting of containers such as high-end alcohol and cosmetics is also increasingly using electronic tags. [0003] In the current prior art, such as the Chinese patent CN200910045793.8, an electronic label anti-counterfeit bottle cap is disclosed, which includes a cover body, an electronic label and an anti-counterfeit top. The inside of the anti-counterfeit top is set as a cavity. It is arranged on the top end of the cover, and the electronic tag is arranged in the cavity. The electronic label anti-counterf...
