Abstract

Radio frequency identification, RFID, uses electromagnetic fields to transfer data wirelessly. Common uses of RFID are entry passes to secure sites, library book logging, or tracking component parts in a production process. Passive RFID tags consist only of an antenna and a microchip, whose shadow can be seen by holding an RFID card up to a light. Passive RFID tags are powered by the RFID reader’s electromagnetic field to receive messages from the RFID reader and transmit messages to the RFID reader.
