Radio frequency identification (RFID) technology uses radiated and reflected RF power to identify and track a variety of objects. A typical RFID system consists of a reader and a transponder (or tag). An RFID reader contains an RF transmitter, one or more antennas and an RF receiver. An RFID tag is simply an uniquely identified IC with an antenna.
Communication between a reader and a tag is via backscatter reflection, similar to a radar system, in the UHF frequencies from 860MHz ...
