03:19 09 Apr 2026

You can build a QR-based contact system by using a backend that acts as a bridge between the user and the vehicle owner, without revealing personal details.

Basic flow:

  1. Generate a unique ID for each user

  2. Store user contact details securely in a database

  3. Create a QR code containing that unique ID

  4. When someone scans the QR:

    • Redirect to a web page

    • Provide a form (message/call request)

  5. Send notification to the owner via API (SMS/email)
