Expansion of Seat Registration System by QR Code for Corona Disaster to Attendance Management System

Abstract

In response to the COVID-19 pandemic, a QR code-based “Seat Registration System” was introduced in April 2020 to track student seating. While convenient, it faced issues such as easy misuse through copied QR codes. To improve security while maintaining ease of use, an enhanced “Attendance Management System” was developed, adding features like classroom layout and real-time attendance status. Launched in April 2022 for general education and expanded in October 2022, the system has been operating smoothly, and this paper reports on its development and implementation.
