This paper deals with the solutions related to the ATM security. We are going to make use of fingerprint or One Time Password (OTP) verification along with the use of ATM pin. In this system, the user can have third party authentication either temporary or permanent. In the whole process, the first party i.e. the banker will maintain a database of the customer including fingerprint and mobile number. The banker will provide the ATM card along with its PIN. For the transaction after entering the ATM pin, the customer will be asked to choose an option either fingerprint or OTP verification. The OTP will be sent to the registered mobile number of the customer through GSM module connected to the system. After authorised verification, the customer will be able to proceed for transaction else after three successive wrong attempts, the ATM card will be blocked for 24 hours and a message will be sent to the registered mobile number
