Fingerprint Based ATM

Abstract

The traditional ATM terminal customer recognition system rely only on bank cards, passwords, and such identity verification methods which measures are not perfect and functions are too simple. Fingerprint Based ATM is a desktop application where fingerprint of the user is used as an authentication. The finger print minutiae features are different for each human being so the user can be identified uniquely. Instead of using ATM card Fingerprint based ATM is safer and secure. There is no worry of losing ATM card and no need to carry ATM card in your wallet. You just have to use your fingerprint in order to do any banking transaction. The user has to login using his fingerprint and he has to enter the pin code in order to do further transaction. The user can withdraw money from his account. User can transfer money to various accounts by mentioning account number. In this paper, a microcontroller based prototype of ATM access system using fingerprint sensor module is implemented. If the fingerprint does not match, then the card will be locked automatically. A PIC16F877A microcontroller is developed by Microchip Technology is used in the system. The necessary software is written in Embedded ‘C’ and the system is tested.
