Finger Print Based License Checking System

This project is designed with Microcontroller, Finger Print sensor, Arm Processor circuit and EEPROM. Finger print sensor is the special type of sensor which is used to identify the human finger print. Finger print sensor is interfaced with microcontroller through the arm processor circuit. The arm processor circuit is used to activate the finger print sensor at the time the finger is placed on the sensor. The related data is stored in the microcontroller. In this project microcontroller is interfaced with EEPROM. The microcontroller transfers and stores the related information to EEPROM. When human places the finger on the finger print sensor, the sensor sends the corresponding data to microcontroller. Here we use microcontroller Atmel AT89C52. It is a flash type microcontroller in which is already programmed. Microcontroller receives the data from the finger print sensor. Then it is compared with stored data if it is correct information displayed in PC If data is not matched microcontroller will display the Authentication Fail on the PC.
