MJS Event Registration
A system event registration and check-in management system with real-time QR code verification, admin dashboard, and audit logging - built with Next.js and PostgreSQL.
MJS Event Registration is a system for managing event attendee registration and on-site check-in. Attendees register via a public form, receive a unique QR code upon successful submission, and are verified at the venue through a QR scanner page. Admins access a protected dashboard with registration management, analytics charts, and full audit logs. The system uses Supabase PostgreSQL via Prisma ORM, Upstash Redis for rate limiting, and NextAuth for session-based authentication - suitable for internal company events as well as client-facing event management needs.
Manual event registration and check-in processes are slow, error-prone, and difficult to audit - especially for mid-to-large scale corporate events where real-time attendee verification and data accuracy are critical.
A web-based registration system where attendees self-register and instantly receive a QR code. On event day, staff use the built-in QR scanner to verify attendance in real time. Admins monitor registrations, view analytics, and access audit logs from a protected dashboard - replacing spreadsheets and manual processes entirely.
