Many common design mistakes should be avoided as they can directly impact QR code scanning and even result in the QR code being unscannable. These common mistakes include:
- Incorrect selection of design colors
- Using a cluttered design
- Improperly placing the logo inside the QR code
- Choosing the wrong font for the CTA
- Using various gradients and shadows
If these factors are not considered when creating the design after generating the QR code, it can lead to serious issues. Failing to prioritize color contrast, having the logo size damage the QR code's lines, creating a design that's too cluttered, using the wrong font for an unreadable CTA, and applying various effects can all result in the QR code being unscannable.
