Because of the several advantageous of RFID like its low cost, small in size also the objects are identified by the computer, use of RFID in many application is increasing today. But RFID may undergo various types of attacks like ghost-leech attack. Attacker has gained access to the information stored in tag. So we need to apply security measures against this. Security measures like RFID enabled smart card, one time password, location sensing and face identity (biometric). There is up gradation from two factor to three factor authentication and now to four factor authentication. In this paper we have taken money transaction application and applied improved four factor authentication scheme which addresses the problem related to RFID.
