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
- Control agent login with rights verification
- QR code scan and ticket data retrieval
- Validation or rejection based on ticket status
- 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.
