history of rf security tags Radio-frequency identification (RFID) uses electromagnetic fields to automatically identify and track tags attached to objects. An RFID system consists of a tiny radio transponder called a tag, a radio receiver, and a See more NFC tags are passive, meaning they don't have any power source. Instead, they literally draw power from the device that reads them, thanks to magnetic induction. When a reader gets close enough to a tag, it energizes it and .

who invented rfid radar
In 1945, Leon Theremin invented the "Thing", a listening device for the Soviet Union which retransmitted incident radio waves with the added audio information. Sound waves vibrated a diaphragm which slightly altered the shape of the resonator, which modulated the reflected radio frequency. Even though this device .
