Radio Frequency Identification (RFID) is the latest phase in the decades-old trend of the miniaturization of computers. RFID transponders are tiny resource-limited computers that do not have a battery that needs periodic replacement. RFID tags are inductively powered by their external reading devices, called RFID readers. Once the RFID tag is activated, the tag then decodes the incoming query and produces an appropriate response by modulating the request signal, using one or more subcarrier frequencies.
