QR code preparation for print and digital use

QR code reliability depends on source content, physical size, contrast, print quality, surrounding quiet space, and the capabilities of the scanning device.

Common applications

• Verified payment or invoice links
• Restaurant, event, or product information
• Guest Wi-Fi access strings
• Portfolio, booking, or contact pages

Codes can be prepared with the QR Code Generator and tested with the QR Scanner.

Release checklist

• Verify the encoded content before publication.
• Maintain a clear quiet zone around the code.
• Use strong contrast, normally a dark code on a light background.
• Test the code at final physical size and viewing distance.
• Test with more than one current mobile device.
