Abstract. This paper reviews attendance management systems (AMS). An AMS (semi) automatically identifies the students in the classroom and makes report on attendees and absentees. A biometrics-based AMS identifies students by reading fingerprints or irises. A radio-frequency-identification (RFID)-based AMS recognizes a student by reading the unique RFID carried by the student. Each recognition method has some advantages and disadvantages. The most common disadvantage of AMSs is that special devices are required. For example, a RFID-based AMS requires RFID readers. After investigating existing AMSs, this paper proposes an AMS that does not require any additional devices as long as every student carries a smartphone and the wireless local network is available in the classroom.
