Confusion anti-counterfeiting method and system based on RFID

The invention provides a confusion anti-counterfeiting method and system based on RFID (Radio Frequency Identification), a plurality of chips supporting high frequency, ultrahigh frequency and double frequency are mixed and introduced into electronic tags of similar commodities, and each chip at least supports one communication protocol. And respectively encoding the chip model and the communication protocol supported by the current chip, and writing the encoded data into the chip, so that the chip has at least one communication protocol code. And scanning the electronic tag of the commodity by using the terminal, verifying the scanned information with the background information, and if the model and the communication protocol code obtained by scanning are completely consistent with the background information, determining that the commodity is a certified product. The anti-counterfeiting method has the advantages that multiple types of labels and corresponding security verification methods are introduced as a
