There is need for improve security in ATM transactions. Due to tremendous increase in the number criminals and their activities, the ATM has become insecure. ATM systems today use no more than an access card and PIN for identity verification. The Personal Verification Number (PIN) not only give good security. The fingerprint is unique and cannot duplicate by others. This paper combine the pin verification and fingerprint recognition technology for identification. With fingerprint recognition technology and pin verification the authors embedded the GSM modem connected to the microcontroller generates the 4 digit one time password and it send to the main user mobile number when the user (main user or nominee user) enroll the fingerprint.
