Abstract

Abstract— In ATM machines the user is identified by inserting an ATM card and authentication is provided by the customer entering a PIN. The PIN provided by the customer is compared with the recorded reference PIN within the bank Server. If the customer forgets the PIN after 3 trials ATM cards are blocked, to reactivate he needs to attend the bank and dothe formalities which could be a time consuming job. So fingerprint biometric is introduced to cut back this sort of error. This project aims at exploring the system to secure ATM pins and passwords with the fingerprint data specified only the legitimate user can access the pins and passwords by providing the valid fingerprint.
