Abstract

This project presents the design and implementation of a long-range RFID attendance system aimed at transforming how educational institutions track attendance by making the process faster, more accurate, and completely contactless. Tradi- tional methods, whether manual roll calls or short-range RFID scanners, often interrupt class routines and leave room for errors or proxy attendance. To address these issues, the proposed system integrates long-range RFID readers, beam sensors, and ESP32 microcontrollers to automatically detect and record attendance as students and faculty naturally walk through designated entry points. The RFID readers capture unique identification tags from several meters away, eliminating the need for users to stop or interact with the system, while beam sensors validate movement and reduce false readings. The ESP32 processes the collected data, filters duplicates, associates each detection with the correct subject and session period, and transmits the information wirelessly via Wi-Fi to a centralized web server. A user-friendly web dashboard allows administrators, faculty, and students to view real-time attendance records, filter by presence or absence, and download reports in CSV or Excel formats, with role-based access ensuring appropriate data visibility. The system’s architecture includes RFID hard- ware optimized for long-range, contactless identification through non-metallic barriers and supports bulk tag recognition, making it suitable for busy entry points. Secure database management ensures persistent storage of attendance logs, while modular web applications provide analytics, usage logs, and period-wise tracking to support academic decision-making. Extensive testing under various environmental and network conditions confirms the system’s reliability and accuracy. By automating the entire workflow, this solution minimizes time wastage, reduces human error, and provides institutions with consistent, trustworthy atten- dance data that enhances operational efficiency and supports timely interventions to improve student performance.
