Dual-ID Attendance System

Accurate and secure attendance tracking is essential in educational environments to monitor student engagement and academic accountability. Traditional attendance systems often rely on single-factor authentication, such as manual entry or basic ID scanning, which leaves room for security breaches and inaccuracies. This research introduces a dual-layered authentication system that integrates Radio Frequency Identification (RFID) with fingerprint biometric verification to enhance security, ensure accurate identification, and streamline the attendance process. The proposed system is built using Arduino-based hardware and custom-developed software, enabling real-time data processing and logging. A group of ten students participated in the experimental evaluation, each assigned a unique RFID tag and fingerprint record. Performance tests revealed an average processing time of 20.61 seconds per individual, with a 0% false rejection rate, demonstrating high reliability and precision. The integration of biometric and RFID technologies not only strengthens authentication but also reduces the complexity often associated with multi-factor systems. The coordinated hardware-software design significantly improves operational speed and data integrity. Overall, the results affirm that the system is a robust, efficient, and scalable solution for modern attendance management in academic institutions.
