Realtime Automated Classroom Attendance Monitoring System Using RFID

Automating attendance systems with advanced features has become increasingly crucial in moderneducational environments to improve efficiency, security, and resource management. The RFID-basedattendance system presented integrates innovative features such as real-time duplicate scan prevention, atimer-based power optimization mechanism, and departure tracking capabilities. The system leveragesRadio Frequency Identification (RFID) technology to accurately record attendance, utilizing amicrocontroller and database integration to manage data effectively. A TFT display provides real-timefeedback, enhancing user interaction by displaying attendance statuses and alerts. The timer-basedshutdown mechanism reduces idle energy consumption, making the system environmentally sustainable.Furthermore, the system tracks student departures, marking absences if students leave the classroomwithout a proper sign-out. Experimental results demonstrate a 98% success rate in attendance accuracy,40% power savings during idle periods, and high user satisfaction due to its intuitive interface. ThisRFID-based system ensures dependable attendance monitoring, enhanced security, and improvedclassroom management, making it a scalable and robust solution for educational institutions. Additionally,the system can be easily integrated with existing school management software for seamless administrativefunctions.
