QR codes are simple to generate, which is exactly why so many end up broken, unreadable, or just plain confusing. Here are the mistakes worth watching for.
Printing it too small
A code that scans fine on a phone screen can be far too small once printed on a poster meant to be viewed from a distance.
Skipping the test scan
It only takes a few seconds to test a code before it goes to print, yet this is the step most often skipped — right up until hundreds of flyers turn out unscannable.
Low contrast colors
Matching a code's colors to a brand palette is great, until the contrast gets so low that cameras can't distinguish the modules from the background.
No context or call to action
A bare code with no explanation gives people no reason to scan it. Always pair it with a short line explaining what they'll get.
Linking to a dead or unfinished page
Nothing kills trust faster than a code that leads to a broken link or a "coming soon" placeholder. Always confirm the destination is live before publishing.
