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 the logo as increasing the size removes data modules
- Low error correction: If you added a logo, keep the error correction High or Very High to offset the loss of modules
- Low Color Contrast: The contrast between the colors of the QR Code (eyes and data) and its background could be low. Lighten the background color and darken the QR Code colors to increase contrast
