Abstract: In these prevailing globalized times; we are more connected with the plastic money where our economic transactions are carrying out through debit or credit cards. The prevailing ATM (Automatic Teller Machine) systems founded on magnetic card & a static PIN. The breaching into the existing system by skimming devices, card trapping, etc. revealing the vulnerability of existing siting creates a hostile atmosphere for the transactions. The proposed system introduces an alternative for the magnetic card and PIN. The proposed system doesn't need any other complex component other than fingerprint sensor additional to existing traditional ATM. Instead of magnetic ATM debit/credit card use chip enabled card which contain only Account number, Name of the customer, Fingerprint and PIN. A fingerprint sensor is an electronic device used to capture a digital image of the fingerprint pattern. The captured image is called a live scan. This live scan is digitally processed to create a biometric template (a collection of extracted features) which is stored and used for matching. The input fingerprint retrieved from the sensor is directly compared with template stored on the card issued by the bank after this authentication, the embedded code initiate the communication with the data server to complete the financial transaction.
