Fingerprint Recognition System with Source Code
This project is based on biometric fingerprint recognition module. It can add new fingerprints and search for existing fingerprints stored in its memory. The microcontroller used is Atmel AT89S52. It provides interface for Switches, LCD and Serial Data to PC. On PC we give software in VB.NET with source code which you can modify to suit your application. We also provide full source code for MCU AT89S52 which you can study and modify as per your application.

About Fingerprint Recognition Sensor Module
The sensor is a solid-state fingerprint sensor that reliably captures fingerprint information. It is designed to integrate into devices for improved security and convenience. The sensor provides a reliable, quick and user-friendly alternative to passwords, PIN's and other forms of user authentication. This fingerprint scanner is capable of gathering and storing unique finger prints. Simply hold your finger on the optical scanner, query the device over serial, and you will be issued a unique ID. Use that ID within your embedded system to determine access levels, time clocks, door locks, etc. Unit includes 4 pin connector cable to connect and read to controller. The outputs is TTL level serial data. A biometric sensor, fingerprint sensor to be specific, also known as the fingerprint reader, is a fingerprint image capture device, the very front end of the biometric fingerprint identification/verification module. The fingerprint sensor captures the fingerprint images, matches the uniqueness of each print read by the sensor and compares it to the one stored in its module or local system database. It consists of optical fingerprint sensor, high performance DSP processor and Flash. It boasts of functions such as fingerprint enrollment, fingerprint deletion, fingerprint verification, fingerprint upload, fingerprint download, etc.
