Finger print Based Authenticated Access Control System

Description

This kit authenticated access control system is designed to make the access control system secure and fault-free. At the time of registration for the system, the valid users need to register themselves with their user fingerprint. Hence, the database will be created for valid users only. If some user wants to open the gate, he will have to scan his fingerprint and if the authentication is done, the gate will be opened. The gate will be closed automatically.

The authenticated access control system kit is the fingerprint scanner is there to scan the fingerprint and store the database inside it. The microcontroller can ask it anytime to check the validity of the preset finger placed on it. If the user is valid then only the microcontroller opens and closes the gate. The gate is controlled with the help of a dc motor driver which driver the motorized gate. The system can be powered up with 12V 1A ac or dc power supply.

The rectifying and filtering circuit is embedded in the system. The communication link between the fingerprint scanner and the microcontroller is the UART communication. The system can be further upgraded and hence can be connected with the system where there can be a large database. The computers can be connected with the system in the future to increase the number of users.
