ATM Authentication with Enhance Security Using GSM

Abstract

Rapid development of banking technology has change the way banking activities are dealt with one banking technology that has impacted positively to banking activities and trans-actions is the advent of automated trailer machine. Using an Automatic Teller Machine, customers can access their bank accounts. ATM s were originally developed as just cash dispensers; they have evolved to include many other bank-related functions such as Purchasing, Postage stamps, Lottery tickets, Train tickets, cash with drawl, money transfer, paying phone and electricity bill beyond official hours. The problem is that sometimes the person stand behind to user will able to watch user pin. And also pin ethically hacked by hackers for their own mechanism. In proposed system we have overcome the problems of manual system which are given below .like a Biometric recognition, Face recognition, IRIS recognition, DNA data with fingerprint identification etc. We can access our account from our mobile without using ATM system keyboard. The main objective of this system is to develop an embedded system, which is used for ATM security applications. In these systems, we used Toll Free number via GSM and this GSM fixed in a ATM system. When user will call on Toll Free number at that time, GSM is in auto answer mode. And user entered the 4 digit pin in his/her mobile. After entering it checks whether it is a valid one or not and allows the customer for further access.
