Abstract

Ambiguously, logbooks and manual entry are alternative mechanisms widely used in traditional systems for attendance monitoring and controlling, which remain ineffective and cause misreporting, proxy attendance, and contentions. This article is a design of an effective automated Graphical User Interface (GUI) for a Camera-Based QR Code Reader Attendance Monitoring System to improve the reliability and speed of manual operations. Utilizing QR (Quick Response) code technology, ID data are read and decoded immediately with imaging equipment. It has a GUI with prompts, feedback, and logging/reports. The development of the proposed system followed the Software Development Life Cycle (SDLC), which organizes system activities into sequential and iterative phases to ensure reliability and maintainability of the system, which stresses an iterative process with stakeholder involvement at every stage of the design. By doing so, they would use real-world needs, rather than fixed specs, to decide what features they should add. Quantitatively investigating the effectiveness of our system, we conducted a study with 112 participants. Weighted mean Score was employed in the analysis of data, resulting in an overall weighted mean score of 4.40, which indicates that performance is “Very Satisfactory”. In particular, the users declared performance efficiency and data confidentiality as strong points of the system, focusing on a good trade-off between computational speed and architectural security. In terms of application, along with practical significance, the system is in favor of the global development agenda 2030; it does contribute significantly towards some of these goals, given its contribution to efficiency and effectiveness in the academic control process through the enhancement of attendance monitoring, by providing non-exclusive creative access to technology. Going forward, some possible pathways include strengthening the system’s ecosystem by supporting biometric authentication, multi-platform mobile compatibility, and advanced predictive analytics to make computing power more sophisticated.
