Abstract

The rapid development of information technology has given birth to online attendance innovations using Quick Response Code (QR Code), utilizing technology to facilitate fast and responsive information exchange. Attendance systems play an important role in monitoring staff attendance and measuring productivity. Currently, the attendance system for TKIT Insan Mulia Manokwari educators still uses a fingerprint machine, so fingerprint identification is slow and attendance is recorded manually. To overcome this, a new QR Code-based attendance system is needed. This research uses the Rapid Application Development (RAD) method which includes requirements planning, system design, development and implementation. The resulting web-based QR Code attendance system simplifies teacher attendance and provides automatic recap reports, increasing data accuracy and reducing manual errors. This system effectively increases the efficiency of school administration. This research can be a reference for developing attendance systems in other educational institutions.
