QR Code Generator Frequently Asked Questions
What information can QR codes store?
QR codes can store various types of data including plain text, URLs, email addresses, phone numbers, SMS messages, WiFi credentials, vCard contact information, and even small files. The maximum capacity is about 3,000 alphanumeric characters.
What's the difference between QR code error correction levels?
Error correction allows QR codes to remain readable even when partially damaged. Low (L) = ~7% recovery, Medium (M) = ~15% recovery, Quartile (Q) = ~25% recovery, High (H) = ~30% recovery. Higher levels create denser codes but provide better damage resistance.
Can I customize QR code colors safely?
Yes, but maintain high contrast between foreground and background colors. Dark foreground on light background works best. Avoid light colors on dark backgrounds as they may not scan reliably. Test thoroughly with different scanning devices.
What size should QR codes be for printing?
Minimum size depends on scanning distance and code density. For business cards, use at least 1x1 inch. For posters, calculate based on viewing distance - generally 1 inch per 3 feet of scanning distance. Always test print quality before mass production.
Are QR codes secure for sensitive information?
QR codes themselves don't encrypt data - they're just a visual representation. Anyone can scan and read the content. For sensitive information, use HTTPS URLs that lead to secure, authenticated pages rather than embedding sensitive data directly.
QR Code Best Practices
- Test QR codes with multiple devices and scanning apps
- Use high contrast colors for better readability
- Include a call-to-action telling users what to expect
- Keep URLs short to create simpler, more scannable codes
- Add your logo or branding carefully to avoid blocking important data areas
- Always test the final printed version before distribution
