Intra Debit Card System using RFID Technology

RFID Radio-Frequency IDentification is one of the technologies that is used for the past few decades for tracking and identification of an object. RFID tag contains unique information wirelessly with computer databases and network for tracking the objects easily. Prior to performing the read/write operation on RFID card, the reader has to make an authentication check. Usually a default key supplied by the manufacturer is used to do the above. This poses a security threat; anyone can now access the contents of the RFID tag. For handling this security threat, we propose a mechanism involving where the RFID reader tag communication has been enhanced by making use of an identity based authentication technology which involves a third party’s authentication. We intend to deploy this security mechanism of the RFID reader and tag access in the scenario of educational institutions; an internal debit card system could be set up. This is particularly beneficial for students of small age to be able to carry out transactions involving the purchase of their uniforms, bags, stationary and other requirements at school. Parents wouldn’t have to worry about going in person to take care of their ward’s monetary needs.
