Abstract: The main objective of this system is to develop a system that will increase the ATM security. However, despite the numerous advantages of ATM system, ATM fraud has recently become more widespread. In this paper, we provide an overview of the possible fraudulent activities that may be perpetrated against ATMs and investigates recommended approaches to prevent these types of frauds..Biometrics technology is rapidly progressing and offers attractive opportunities. In recent years, biometric authentication has grown in popularity as a means of personal identification in ATM authentication systems. An 8-bit ATmega16 microcontroller developed by Microchip Technology is used in the system. The necessary software is written in AVR studio programmer and the system is tested.

Keywords: ATmega16 microcontroller, Finger print recognition, Liquid Crystal Display, DC motor.
