Sometimes, the reading of the QR code can fail. If a QR code is damaged or dirty, it can lead to difficulties when scanning with a QR code reader. On the other hand, one of the reasons for this could be the low-quality QR code printing. The background color of the QR code or the lighting conditions can also contribute to the failure of QR code scanning.
