Locker Key Management System

This project presents a smart and secure RFID-based Locker Management System integrated with Wi-Fi connectivity for real-time monitoring and control. The system is designed to ensure multi-level access security using RFID authentication for both the client and the admin (master). The core functionality is managed using an Arduino connected to an ESP-01 Wi-Fi module, enabling seamless communication with a Node.js backend server. A key feature of the system is its mandatory internet connectivity; the locker system will not operate without an active Wi-Fi connection. A white LED indicator confirms successful Wi-Fi connection. Upon scanning the admin RFID, the locker opens. However, to close the locker, the system requires an additional level of verification: both the client's RFID and the admin's RFID must be scanned again, ensuring that both parties are present and authorizing the closure. The system also includes real-time alerts, activity logs, and status updates through the server. It is designed for use in environments such as co-working spaces, gyms, hostels, and smart offices, where secure and monitored storage is essential. This solution improves traditional key-based systems by adding intelligent control, remote monitoring, and enhanced security.
