Why won't my QR code scan?
A checklist of the reasons a QR code fails to scan, from contrast and quiet zones to expired links and dead redirects, each with the fix. Then test the code to be sure.

Questions
My QR code scans on screen but not on the print. Why?+
Print is smaller, lower contrast and further from the camera. The usual causes are a size that is too small for the distance, ink spread on textured paper, or a busy background touching the code.
The code scans but the page does not open. Why?+
The link is the problem, not the code. Expired short links, a dead redirect, or a site that blocks in-app browsers. A dynamic code lets you fix the destination without reprinting.
Does a logo in the middle break the code?+
It can, if it covers too much or sits on a finder pattern. Keep any logo under 20% of the area and away from the corners, and raise error correction.
How do I check without printing a hundred copies?+
Use the tester on this site. It simulates smaller, blurrier and tilted scans on the image itself.
