QR code guides
What actually matters when you're about to commit a QR code to print.
Dynamic vs static QR codes
A static QR code has the destination baked into the image. A dynamic one points at a link you control. Here's when each is the right call.
How to change a QR code after it's printed
Whether you can change where a printed QR code goes depends entirely on which kind you printed. Here's how to tell, and what to do either way.
Do QR codes expire?
QR codes don't expire on their own. What breaks is the link inside them, or the service running the redirect. Here's the difference.
Why isn't my QR code scanning?
Printed QR code won't scan? It's almost always size, contrast, quiet zone or finish. Work through these in order.
What size should a QR code be?
The rule is one tenth of the scanning distance, with a 2cm minimum. Sizes for business cards, flyers, posters, packaging and signage.
