RFID Base Attendance System with UUID Verification

Due to security vulnerabilities and a lack of geo-fencing, traditional RFID-based attendance systems might be troublesome in certain circumstances. This research proposes an enhanced RFID-Based Attendance System with UUID Verification that enhances automation and security by integrating geo-fencing with Bluetooth Low Energy (BLE) UUID authentication. Using an ESP32 microcontroller, the gadget scans RFID cards. For further authentication, it connects to a mobile app via Bluetooth Low Energy (BLE). Every student receives a unique UUID that is entered into the database in addition to the RFID card scan. Because of geo-fencing, attendance can only be tracked when a student is physically present inside a specified area. This hybrid approach provides a secure, cost-effective, and power-efficient solution for tracking attendance in workplaces and educational institutions while lowering the risk of RFID cloning.
