A Smart Attendance Management System Using NRF51822 BLE Module and Mobile Application

The rapid advancement of mobile technology has revolutionized traditional attendance systems, offering efficient and user-friendly solutions. This research paper presents a Mobile Attendance System that uses Bluetooth Low Energy(BLE) technology via the NRF51822 module to enable students to mark attendance through a mobile app. The app allows students to log in, mark attendance by detecting BLE signals, view attendance records, and receive announcements, while ensuring data integrity by linking attendance to the unique device ID of their registered mobile device. In cases of device loss, students can request a mobile change, subject to admin approval. The integration of BLE technology ensures a seamless, contactless attendance process, making it ideal for modern educational environments. This system improves administrative efficiency, ensures data accuracy, and enhances communication between students and administrators. The project highlights the potential of mobile and BLE technologies to modernize attendance tracking, offering a scalable and innovative solution for educational institutions.
