What is it?

Radio-frequency identification (RFID) uses small tags to store and transfer data wirelessly to a reading device for the purpose of identifying and tracking an object.

RFID tags take many forms, including labels, plastic cards, keyfobs, even tiny sterile microchips that can be injected under the skin of animals, including humans.

There are three categories of RFID, passive, active, and hybrid.
  • Passive RFID tags require no power source, but their readable range is limited to a few centimetres.
  • Active tags contact a battery, enabling them to always broadcast a signal. Their range can be ten metres or more.
  • Hybrid tags contain a battery, but are only activated in the presence of a reader, extending the range somewhat from passive tags.

There are several standard frequency ranges in which RFID systems operate. The best fit is determined by the required distance at which the tags need to be read, and what types of obstructions might interfere.
