Printing tips that boost scan rate

Use dark on light and avoid textured backgrounds.
Keep a generous quiet zone around the code.
Do not stretch or blur the QR code.
Keep redirect chains short and landing pages fast.

More QR best practices

Size is only one piece. Most scan failures come from layout issues, low contrast, or missing quiet zone.
