Making a desk-display QR code easy to scan

Generate the code with QR Code Generator, then test the printed or displayed version with more than one phone. Keep a clear quiet zone around it, use strong contrast, and avoid glossy reflections.

Put a short label and the destination domain nearby so people know what they are opening. Do not encode a secret or a link that may expire unexpectedly. Test from the distance at which someone would naturally hold a phone over the desk.

Where will the code be placed?
