Tips & Best Practices
Use appropriate sizing - minimum 2cm x 2cm for print, larger for distant scanning scenarios.
Use higher error correction levels (Q or H) for outdoor use or when QR code might be damaged.
Always test QR codes with multiple devices and scanning apps before final distribution.
Maintain strong contrast between dark and light colors for optimal scanning reliability.
Include scanning instructions like 'Scan with camera' for better user adoption.
Use URL shorteners for long links to create simpler, more scannable QR codes.
Place QR codes at eye level, well-lit areas, and accessible locations for easy scanning.
Use dynamic QR codes for content that changes frequently to maintain link validity.

Frequently Asked Questions
What's the maximum data capacity of a QR code?
QR codes can store up to 4,296 alphanumeric characters, 7,089 numeric characters, or 2,953 binary characters depending on the version and error correction level used.
Which error correction level should I choose?
Level L (7% recovery) for clean environments, M (15%) for general use, Q (25%) for outdoor/industrial use, and H (30%) for harsh conditions or when QR code might be partially damaged.
Can I customize QR code colors safely?
Yes, but maintain high contrast. Dark foreground on light background works best. Avoid light colors on dark backgrounds as many scanners may have difficulty reading them.
What's the minimum size for printed QR codes?
Minimum 2cm x 2cm (0.8 inch) for close-range scanning. For scanning distances over 50cm, use larger sizes following the 10:1 rule (10cm scanning distance = 1cm QR code size).
Are QR codes secure for sensitive information?
QR codes themselves don't encrypt data. For sensitive information, use HTTPS links to secure pages, avoid embedding passwords directly, and consider dynamic QR codes for better control.
