A QR code may not work if there are issues with its color contrast, size, print quality, or if it has expired or contains invalid content. Below are the 7 reasons why your QR code might not be working:
Print quality: If the QR code is not printed in high quality, the scanner may not be able to scan or read it, which prevents it from working.
Size: If the QR code size is inappropriate, it may affect scanning and prevent it from functioning properly.
Lighting: Scanners may struggle to read QR codes in various lighting conditions. The QR code may not be scanned or work properly if the lighting is not optimal.
More content: If too much content is included in the QR code, it can create a cluttered appearance, making it difficult to scan and preventing its function.
Color contrast: If the QR code design uses overly complex colors and doesn’t adhere to proper color contrast, it can cause difficulties during scanning and may not be scanned.
Expired QR code: If payment for the QR code is not made, it will expire and not work until it is made again.
Deleted content: If the content embedded in the QR code is deleted or becomes invalid, the scanner won’t be able to access that content, and the QR code will not work.
