I’d love to explain what’s wanted and why this setup is a bit more advanced than just generating regular QR codes.
This isn’t just about creating a QR image — the system involves:
✅ Generating 100 unique QR codes, each mapped to a specific guest.
✅ Building a back end system to verify if a QR code has been used or not.
✅ One-time-use enforcement – once a code is scanned, it becomes invalid.
✅ Secure data handling, so no one can reuse or forward the invitation.
✅ Optional: Landing or confirmation page for guests when they scan the code.
This helps ensure that:
• The event is secure and controlled.
• No one can misuse or forward the invitation.
• I can track attendance if needed.
This includes setup, development, testing, and support.
Please submit your offer.
