If you created a custom-designed QR Code but the QR Code scanning application on your smartphone is not detecting it, then it could be because of the following reasons:
Large size of logo: Decrease the size of logo, as larger the size, more will be the data modules removed
Curved or Uneven Surface: A QR Code will be scannable only if it's printed on a flat and even surface
Low Color Contrast: The contrast between the colors of the QR Code elements (eyes and data) and its background could be low. If your QR Code is dark colored, keep the background color light and vice-versa
If your QR Code is still not scannable, you can email the image to [email protected] and our team will personally help you resolve the issue.
