To make sure your QR code works reliably across different devices and situations, here’s a checklist of things to keep in mind before using it in the real world:
✅ Check contrast and color
Use high contrast between your foreground (QR code) and background. A dark code on a light background works best. Avoid using similar hues or gradients that can make the pattern hard to distinguish.

✅ Test the size
Make sure the code is large enough to scan from the intended distance. For printed codes, a general rule is:
- Minimum 2 cm × 2 cm for close range
- At least 1 inch of code for every 10 feet of scan distance
✅ Avoid blurry or pixelated prints
When printing your QR code, use a high-resolution format like PNG or SVG. Avoid resizing small images which may blur the code.

✅ Keep quiet zones clear
The “quiet zone” is the empty space around the code. Don’t crop too closely—this space is important for scanners to detect the code properly.
✅ Be cautious with logos and custom designs
You can add a logo or customise your QR code, but avoid overdoing it. Make sure your design doesn't interfere with key QR patterns and always test customised codes with multiple devices.

✅ Test with real devices
Once your QR code looks good on screen or print, try scanning it using several devices and apps (iPhone, Android, etc.). It’s the easiest way to catch issues before going live.
