The system is designed to pass only verified users by scanning fingerprints and blocking unverified users. Our system consists of a fingerprint scanner connected to a microcontroller circuit. In the registration mode, the system can register up to 20 users and store their identity with the respective identification numbers in the system memory. After storage, the person first needs to scan his finger on the scanner. The microcontroller now checks the validity of people's fingerprints. If the fingerprint is authorized, the microcontroller now sends a signal to an engine controller. The motor driver now operates a motor to open a damper. This ensures that only authorized users can enter the examination section and that unauthorized users can not enter without human intervention.
