A QR code doesn't work if there are issues with its color contrast, size, print quality, or any factors that hinder scanning, or if it has expired or the content within it is invalid. 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 size of the QR code is not appropriate, it can interfere with the scanning process, and in some cases, the scanner may not be able to scan it, which stops it from functioning.
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.
