Real-Time Web-Based Online Attendance Management System with Automated Record Generation: A Hybrid MERN Stack Approach

This paper presents a novel web-based system for real-time online attendance management coupled with automated record generation. The system integrates a MERN stack–based architecture for secure and reliable attendance handling, MongoDB for persistent data storage, and a React-based frontend for interactive user access. Unlike conventional manual or semi-automated attendance systems, the proposed approach incorporates intelligent data validation, role-based access control, and contextual session handling to maintain accuracy and consistency across multiple class sessions. The system achieves an average attendance accuracy of 94% during evaluation and provides sub-2-second response time for real-time attendance marking and retrieval. Experimental results demonstrate the system's effectiveness in educational institutions, classroom environments, and large-scale academic management scenarios.
