QR Code Best Practices
- Always test your QR code before printing or publishing
- Use high contrast colors (dark foreground, light background) for better scanning
- Make sure the QR code size is appropriate — at least 2cm × 2cm for print
- Choose appropriate error correction: higher levels allow the code to be read even if partially damaged
- Avoid placing QR codes on curved or reflective surfaces
