NFC Wireless Door access system

Abstract

The Dynamic NFC Wireless Door Access System is an IoT-based access control solution that leverages NFC technology and centralized server authentication to manage and secure physical entry points. Designed to improve facility security and streamline access management, the system uses a Raspberry Pi 4B as a central server that stores user credentials in a database and verifies access requests by comparing NFC card data with stored records. By automating the access process through NFC card recognition, secure data transmission, and real-time relay activation, the system minimizes manual oversight, enhances control, and reduces the risk of unauthorized access.Equipped with ESP32 Wi-Fi modules at each access point, the system reads data from an NFC card when tapped by an employee. The data is then sent to the server for verification. If authentication is successful, the system activates an electromagnetic lock, granting entry. Designed for environments requiring secure access, the Dynamic NFC Wireless Door Access System is ideal for businesses, government facilities, and educational institutions.
