Abstract
Managing attendance in institutions and organizations has become a difficult challenge. The ability to compute attendance becomes a major task as manual computation produces errors, and also wastes a lot of time. Radio-frequency identification (RFID) and Biometrics have been individually used to solve the problem of attendance in recent years. RFID has a major security and integrity problem known as buddy punching. Although biometrics solved the security problem its complexity and longer execution time due to real time interaction with a central server which could be many distance away, has created a major setback to its implementation. Therefore, a hybrid attendance system using RFID and biometrics was developed. Students’ environment was considered for the investigation. In this paper, a method to solve attendance problem through coordinated hardware and software design handshaking data communications among RFID tag, RFID reader and fingerprint scanner serially interfaced to the digital computer system was proposed. Biometric data and personal details are stored on the RFID tag to secure the tag and eliminate the dependency on the real time central server for authentication. Performance was evaluated in terms of read time with and without wallet, encoding, attendance, and enrollment feature using 50 trials. The results showed that average read time of 831,294ms with standard deviation of 35,75656254ms was obtained without barrier while with barrier (wallet), the average read time of 831,0600ms and standard deviation of 34,14399879ms were obtained. The results indicated high speed performance from coordination of the hardware and software and also the performances with and without wallet were almost the same, indicating no effect. The proposed method was able to achieve data integrity and security due to biometrics, low complexity due to RFID and average execution time of 0.831sec due to its structural programming pattern and data header structure.
