Radio frequency identification (Radio Frequency Identification, RFID) technology is widely used to logistics
The numerous areas such as industry and retail business, effectively increase the efficiency of management, and human cost is greatly saved.Radio-frequency recognition system by
RFID electronic label is formed with RFID reader, and the course of work is that RFID reader generates the electromagnetic wave of specific frequency and leads to
It crosses the mode that space misfortune is closed to send and (also referred to as send and put question to signal), when RFID electronic label enters the reading of RFID reader
Take apart from when, RFID electronic label is that the electromagnetic wave that can receive the enquirement signal and send RFID reader is reversely dissipated
RFID reader (replying answer signal) is returned to after penetrating coupling.
Radio Frequency Identification Technology has huge application potential in anti-counterfeit field.In the industries such as drinks, tobacco and drug, one
There is counterfeit product in denier, it will brings immeasurable loss to society and individual.The production circulation of these products uses, and needs
There are safely and effectively anti-counterfeit measures.Paper substrate printing anti-counterfeiting technology (such as laser anti-counterfeit, digital anti-counterfeiting etc.) do not have uniqueness and
