Smart ATM Access and Security System using RFID and GSM Technology

Abstract

The aim of this paper is to implement smart ATM card. Now-a-days we use ATM card frequently for shopping , cash withdrawal etc..A single user may have different bank accounts, so the user obviously have many ATM cards .For user friendly access , instead of many ATM cards we compact all into a single ATM card with enhanced security by providing OTP. We also avoid the problem of skimming. The enhanced security of money transaction in ATM system is carried out by RFID. After getting entry customer has to place ATM smart card in ATM machine. Then ATM machine will automatically generates a 4-digit code i.e. OTP. And that code will be message to the customer’s registered mobile number through GSM modem which is connected to ARM 7. Here customer has to enter this code. After entering OTP, System will check whether entered code is a valid one or not. And if it is valid, a list of bank displays, select a bank and it will ask for 4-digit ATM pin, which is fixed. If that 4-digit code match with the entered pin code then system is allowed for further accessing. ATM will show options like cash withdrawal, cash deposit etc..
