An devices called RFID tags or transponders. An RFID tag is a small object that can be attached RFID tag is a small object that can be attached to or incorporated into a product, animal, or to or incorporated into a product, animal, or person. RFID tags contain silicon chips and person. RFID tags contain silicon chips and antennas to enable them to receive and respond antennas to enable them to receive and respond to radio-frequency queries from an RFID to radio-frequency queries from an RFID transceiver. transceiver.

Passive tags require no internal power Passive tags require no internal power source, whereas active tags require a source, whereas active tags require a power source.power source.Source: RFID Journal OnlineHistoryHistoryThe most primitive form of RFID was The most primitive form of RFID was actually discovered by the Germans. They actually discovered by the Germans. They found that if their planes rolled in a certain found that if their planes rolled in a certain way as they returned to base it would way as they returned to base it would change the radio signal that was reflected change the radio signal that was reflected back. back.
