QR code checks before printing or sharing
QR codes are simple to create, but scan reliability depends on content length, contrast, quiet zone, size, and final placement.
Test real devices
Scan the code with multiple phones and camera apps before using it in print, packaging, signage, or events.
Keep contrast high
Use dark foreground on a light background and avoid low-contrast brand colors that reduce scan accuracy.
Preserve quiet zone
Leave enough margin around the code so surrounding text, logos, or borders do not interfere with detection.
Verify destination
Open the final URL after redirects and confirm tracking parameters, HTTPS, and mobile landing pages behave correctly.
A practical example, an edge case, and a maintainer note
Edge case
Dense data, low contrast, a small quiet zone, glossy material, or a redirect requiring cookies can make an otherwise valid code fail.
Maintainer note
I keep the destination short and editable through a controlled redirect, then test the complete redirect chain on mobile.
