The Radio Frequency Identification (RFID) system
  • 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; a radio receiver and transmitter.
  • When triggered by an electromagnetic interrogation pulse from a nearby RFID reader device, the tag transmits digital data, usually an identifying inventory number, back to the reader.
  • This number can be used to track inventory goods.

There are two types of RFID tags:
  • Passive tags are powered by energy from the RFID reader's interrogating radio waves.
  • Active tags are powered by a battery and thus can be read at a greater range from the RFID reader; up to hundreds of meters.
