Human identification is a field very significant and which has undergone rapid changes with time. An important and very reliable human identification method is fingerprint identification. Fingerprint of every person is unique. So, this helps in identifying a person or in improving security of a system. Finger print of a person is read by a special type of sensor.   In this project we use a fingerprint module to read one’s identity to start the equipment. For this we use a microcontroller to enable the ignition system if the matching between scanned data and the already existing data is correct. Comparison is done inside the fingerprint module itself and its output is given to microcontroller. The sensor used is R303A. If the finger prints match with the predefine stored finger print, then microcontroller will access the vehicle door to let the person in. Otherwise, it’s not possible. In this we are using switch to store and delete finger print. The status of the project will display on LCD. Here DC motor works as a vehicle. Microcontroller used is Arduino nano microcontroller.  

This project provides us learning’s on the following advancements:  

1. Interfacing of Fingerprint sensor with microcontroller.
2. Embedded C programming.
3. LCD working.
4. DC motor working.
