Problems solved by technology
[0003] Today’s commonly used RFID anti-counterfeiting methods include using fragile materials such as fragile paper and ceramic sheets as substrates or base antennas. The chip has a security algorithm and supports identity authentication. When RFID is transferred, the antenna will be damaged and the label cannot continue to work. ; But only the antenna is damaged by this method, and counterfeiters can also package the chip with a new antenna to realize the multiplexing of the label, and the anti-counterfeiting effect is poor

The invention provides an RFID electronic tag anti-counterfeiting method, which comprises the following steps that at least three electric connection salient points on a chip of an RFID electronic tag are connected with a radio frequency communication coil and an anti-tamper detection coil, and the radio frequency communication coil supplies energy to the RFID electronic tag through electromagnetic coupling; an encryption and decryption algorithm for identity authentication is built in a chip of the RFID electronic tag; the RFID electronic tag is attached to a commodity seal, the tamper-proof detection coil is connected with the commodity seal, and the tamper-proof detection coil is disconnected when the tamper-proof detection coil is used for the first time; and a detection instruction is sent to the RFID electronic tag, and the RFID electronic tag returns state information about whether the tamper-proof detection coil is damaged or not. The method supports identity authentication, the chip can be effectively prevented from being transferred and reused, and the anti-counterfeiting requirement of a product is met.
Description
technical field [0001] The invention relates to the technical field of anti-counterfeiting electronic tags, in particular to an anti-counterfeiting method for RFID electronic tags. Background technique [0002] In RFID (Radio Frequency Identification Technology), because each RFID tag is unique, a one-to-one correspondence can be established between the RFID tag and the product. RFID is often used in the field of anti-counterfeiting, such as anti-counterfeiting of valuables such as wine and medicine. . [0003] Today’s commonly used RFID anti-counterfeiting methods include using fragile materials such as fragile paper and ceramic sheets as substrates or base antennas. The chip has a security algorithm and supports identity authentication. When RFID is transferred, the antenna will be damaged and the label cannot continue to work. But only the antenna is damaged by this method, and the counterfeiter can also realize the multiplexing of the label by packaging the chip with a ...
