QR code guides
Plain answers to the questions people ask before they print a code, with the steps to do it.
How to change a QR code after it is printed
If the code is dynamic, you change the link in your dashboard and the printed code follows. If it is static, the link is baked in, but there are still options.
Static vs dynamic QR codes
Both scan the same way. The difference is what is stored in the pattern, and that decides whether you can edit it, track it, and whether it depends on a service.
Do QR codes expire?
A QR code itself cannot expire. What can stop working is the link inside it, and that depends on the kind of code and the service that made it.
What size should a QR code be?
Make it at least 2 cm (0.8 in) wide for things read up close, and about one tenth of the scanning distance for anything read from further away.
QR code not scanning? How to fix it
Most scanning problems come from the design or the print, not the phone. Work through these causes in order.
How to scan a QR code
On most phones today you do not need an app: open the camera, point it at the code, and tap the link that appears.
How to make a QR code with a logo
A logo in the middle works because QR codes carry spare data. Keep the logo small, keep the corners clear and keep the contrast high, and it will scan.
How to track QR code scans
You can only track a dynamic code, because only a dynamic code passes through a server when it is scanned. Here is how to set it up and what to look at.
How to make a QR code for a Google Form
Copy the form’s share link, turn it into a QR code, and print it or put it on a slide. People scan it and the form opens on their phone.
How to set up a restaurant menu QR code
Print one code per table, point it at your menu, and update the menu whenever prices or dishes change. The table cards never need reprinting.
How to put a QR code on a business card
A QR code lets people save your details in one scan instead of typing them. Choose what it opens, keep it at least 2 cm wide, and leave space around it.
QR code size calculator
Enter how far away people will scan from and what the code holds. You get the smallest width that scans reliably.
