Comparison and Performance Analysis of App and Web-based One-stop Attendance Management

This paper presents the structure of an electronic attendance system composed of OAA (One-stop Attendance and Absence)-server and client. We compare simultaneous check, fraudulent attendance, prevention of leaving the classroom, and extra equipment according to check methods, and also present a method of app and web-based attendance management. NFC and BLE-based app and location-based web for attendance management were applied to classrooms. Issues with electronic attendance management and resolution methods were also presented. RESTful web service was defined for attendance management and performance analysis was conducted according to thread numbers of OAA-server and parser types of XML and JSON.
