Design issues
Low contrast, transparent backgrounds, busy images behind the code and tiny modules can make scanning unreliable. Keep the QR code clear, high contrast and large enough for the viewing distance.
Printing issues
Blurry prints, glossy reflections, folds, curved surfaces or damaged stickers can reduce scan reliability. Always test a real printed sample before production.
Destination issues
Sometimes the QR scans correctly but opens a private file, expired link or broken page. Dynamic QR codes help because you can update the destination after printing.
