Ayojanix: Design and Testing of a QR-Based Event Management System for Colleges
Year: 2026
Type: article
Abstract: Colleges often manage events with separate tools such as Google Forms, paper attendance sheets, spreadsheets and WhatsApp groups. This causes long queues at entry, proxy attendance, food waste and certificates that are easy to fake. This paper presents Ayojanix, a web-based event management system built with React, Node.js, Express and a PostgreSQL database accessed through Prisma ORM. Students register online and receive a unique QR code pass. Volunteers scan the pass at the gate, and the server rejects invalid, wrong-event and already-used passes to stop proxy entry. The system uses role-based access control (RBAC) with JWT authentication for four roles: Admin, Organizer, Volunteer and Participant. A rule-based decision support module predicts food demand, analyses feedback sentiment and suggests volunteers, budget and venue. Certificates include a QR code for public verification. Functional testing confirmed that the system correctly accepts valid passes, rejects duplicate scans, supports manual pass entry, calculates food demand as designed and verifies certificates.
