Abstracts: Before this system only password base or fingerprint base security system was used. But we have synchronized this it’s call double security. For security purpose we use electromagnetic relay. In this project we use fingerprint module as main input. By using add finger, delete finger we can add or delete fingerprint. This input is given to the micro controller. The output will be taken from micro controller, LCD, relay or buzzer.
