Bluetooth Based Presence Logger

Attendance management is an essential part of both educational institutions and workplaces, yet traditional methods often prove to be time-consuming and prone to human error. Manual processes such as roll calls or paper-based records are inefficient and can easily lead to issues like proxy attendance. To address these challenges, this research introduces a Bluetooth-Based Presence Logger, an automated attendance system that leverages Bluetooth Classic technology available in most modern devices. The system automatically detects and identifies nearby registered devices using Bluetooth scanning and validates them through a secure backend server before marking attendance in real time. The proposed architecture integrates a React Native mobile application for instructors, a Node.js-based backend for device validation, and a MySQL database for reliable data storage and management. By automating the attendance process, this solution aims to minimize manual effort, eliminate errors, and enhance overall accuracy. Furthermore, the system emphasizes cost-effectiveness, ease of deployment, and user privacy, making it a practical and scalable approach for modern educational and organizational environments.
