Key takeaway

Check that the destination URL will remain available and is easy for users to trust.

Always test a generated QR code

A QR code is not useful simply because an image was generated successfully. The encoded content, size, contrast, display distance, and scanning environment all affect reliability. Test the finished code with a phone camera or common scanner before publishing it.

Details that are easy to miss

Common mistakes include making the code too small, using weak contrast, adding an oversized logo, or encoding an unnecessarily long URL. Printed materials should be tested at their real size.

A practical example

Example: a QR code that scans easily from a computer screen may fail when printed on a small card. Test it at different distances and under the lighting conditions where people will actually use it.
