<![CDATA[The development of digital technology in education has encouraged the implementation of modern information systems, one of which is a Quick Response Code-based attendance system. This study aims to design and develop a student attendance information system that uses Quick Response Code cards, connected to a mobile web application, to assist teachers in recording attendance at SMP Negeri 3 Gadingrejo. The method used in the development is a waterfall approach with the steps of needs analysis, design, implementation, testing, and maintenance. This system makes it easy for students to record attendance by scanning the prepared Quick Response Code, so that attendance data is immediately recorded automatically and in real time into the system. The results of the blackbox test method showed that all features functioned well without any problems. In addition, trials with teachers and students showed a high level of satisfaction with the ease and efficiency of the system. It is hoped that this system can replace the manual method that is still used, improve the accuracy of attendance recording, and support the digital transformation of school administration.]]>
