CheckIn Mobile

CheckIn Mobile

Mobile application developed to manage participant check-ins at TDEV Festival 2024. As Lead Tech, I designed a reliable solution to ensure smooth and secure access control during the event.

Main Features#

  • QR code scan: Instant validation of electronic tickets
  • Identity verification: Display of holder information (name, email) for visual verification
  • Special case handling: Valid, already scanned, or invalid ticket with clear feedback
  • Offline mode: Operation without connection with automatic synchronization when network returns
  • Real-time tracking: Entry statistics accessible via dashboard for organizers

Tech Stack#

  • Flutter: Cross-platform Android/iOS application
  • Supabase: Database and real-time synchronization
  • Resend.com: Email confirmation sending

Workflow#

  1. Control agent login with rights verification
  2. QR code scan and ticket data retrieval
  3. Validation or rejection based on ticket status
  4. Immediate synchronization with central database

Results#

The application significantly reduced waiting times at the entrance while ensuring effective anti-fraud control. The offline mode proved particularly useful during peak times with saturated network.
