QR Code Not Working? Troubleshooting Checklist

Fix common QR scanning problems involving size, contrast, quiet zones, damaged codes, glare and destination URLs.

Why a QR code may fail

A QR can look correct on a screen and still fail when printed too small, blurred, low contrast, cropped or covered by a logo. The destination can also be invalid or unreachable.

What to do next

  1. Choose the simplest QR type that matches the user action.
  2. Generate the code.
  3. Test it from the intended distance and device.
  4. Only then publish or print it.
