- Do not try to reduce or resize generated QR code white border. The white border around QR code is known as the quiet zone. The quiet zone is usually white or a light color. Quite Zone of generated QR code should be at least 4 times the width of the black modules of your QR code.
- Prefer larger sized QR code. It can be scanned with even low resolution cameras and even it can be scanned from long distances.
