WebSocket based Smart Attendance System.

Attendance systems are a critical tool to track attendance in various organizations. The integration of Internet of Things (IoT) technology has brought new advancements to attendance systems, with the inclusion of biometric sensors. Biometric sensors, such as fingerprint or facial recognition, ensure the accuracy of attendance records by verifying the identity of the individual. This paper focuses on the implementation of a smart attendance system that leverages the latest IoT technology. The system utilizes a compact and powerful microcontroller board, the ESP32, with in-built Bluetooth and Wi-Fi module for real-time communication through webSocket. The ESP32 also has a low power functionality, operating on a voltage of 3.3V, making it an ideal choice for IoT applications. By combining biometric sensors with webSocket, an instant communication protocol, attendance systems can deliver real-time updates on employee attendance. This allows for increased efficiency, accountability, and security, making IoT-enabled attendance systems an ideal solution for modern businesses. [ABSTRACT FROM AUTHOR]
