bank locker fingerprint, LCD and 8051

Finger print based security system can be used at many places like Industries, Offices, and Colleges or even at our home.
This project is a fine combination of “Biometrics technology” and “Embedded system technology”. Fingerprint sensor is the main part of this system. It makes use of Biometric sensor to detect fingerprint. It is also called as Biometric sensor. Fingerprint sensor uses various types of techniques like ultrasonic method, optical method or thermal technique. In this project we have used optical fingerprint sensor. Main blocks of this project are Microcontroller, Fingerprint module, Buzzer, Relay, Keypad, LCD display and Motor. User has to place his/her finger on the optical sensor part of fingerprint module. We have seen Password based security system RFID based security system. The main feature or speciality of fingerprint is that it is unique. It gives this project the high level security than other security systems. Person recognition using the Fingerprint identification is used since a long time. Most common example is use in the criminal cases.
