The Radio Frequency IDentification (RFID) system uses two main components namely the RFID card and the RFID reader. The RFID card is similar to magnetic cards except the communication protocol used and the medium of transmission. Here in RFID, the medium for communication wireless whereas in magnetic card it is different. Wireless supports fast and distant accessing instead of coping the card to the reader as if in magnetic cards. The communication protocol used by the RFID card and the reader is weigand.
