What to do when the design of a QR code does not work?

Try one of the following actions if your QR code is not readable after customizing it

When you finish designing your QR code, it is important that you scan it from your end using whichever mobile device/QR code reader you have at your disposal.

Here are a few things you can change if the notification reads that the QR code might not be readable:

  • Try increasing the contrast between the colors
  • Check the color contrast and logo dimensions
  • Reupload the logo after rescaling its size with an image editor
