The Problem

SideShade, an event management company, needed a reliable mobile solution to verify attendee tickets at venue entry points — replacing error-prone manual checks that caused long queues and created fraudulent entry risks.

Architecture

Built a React Native mobile application with integrated QR code scanning, Firebase for cloud-synced attendee data, and SQLite for offline capability during events with intermittent connectivity. The app provides instant ticket validation, one-time invalidation to prevent reuse, and real-time check-in statistics.

Results

  • Instant QR ticket validation with offline SQLite fallback
  • Firebase-synced attendance records updated in real time
  • One-time ticket invalidation preventing fraudulent re-entry
  • Deployed for live events under SideShade event management
