The basic aim of this paper is to study the system, which is used for ATM access to cash withdrawal with more security. In this system, Bankers will collect the customer finger prints and mobile number while opening the account then only customer can access ATM machine. The working of system will start when our customer goes at ATM center. First there is switch for entry. After getting entry customer has to places his finger on the finger print module. Then system will check for user identity and checks validity of finger if it finds as a valid then ATM machine will ask to customer for 4-digit ATM pin, which is fixed. If that 4-digit code match with entered pin code then system will automatically generates another different 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 again .After entering OTP, System will checks whether entered code is a valid one or not. And if it is valid, the customer is allowed for further accessing. ATM will show options like cash withdrawal, cash deposit. Also purpose of using Temperature sensor and tilt sensor is to provide security for ATM Terminal.
