College Event Management System
Fest registrations, QR entry passes and volunteer duty rosters

Overview
Organisers publish events with seat limits and team sizes, students register individually or as a team, and each confirmed entry gets a signed QR pass. Volunteers scan passes at the gate from a phone browser, which marks attendance and blocks reuse. Coordinators see live registration counts and can assign volunteers to desks and time slots.

- 01Solo and team registration with seat caps and a waitlist
- 02Signed QR passes that cannot be forged or scanned twice
- 03Phone-browser gate scanner for volunteers, no app install
- 04Role-based access for admin, coordinator and volunteer
