How can I know if the QR code will read properly?

It is worth checking that your QR code scans cleanly before you send it to print, because a code that reads fine on screen can still fail once it is shrunk onto a card or flyer.

• Download a free QR reader from the Apple App Store or Google Play. Most modern phone cameras also scan codes without any extra app
• Point your phone at the code on your screen and confirm it opens the right link before you upload the file
• Print a proof at the final size and test it again, since scaling changes how small the code's modules become
• Leave a clear quiet zone around the code so nearby graphics do not interfere with the scan
• Use strong contrast, dark code on a light background works best
