About QR Codes
QR (Quick Response) codes are two-dimensional barcodes that can store various types of data and be scanned by smartphones and QR readers.
Common uses:
- Website URLs
- Contact information (vCards)
- Wi-Fi network credentials
- Product information
- Event tickets
- Payment information
- App download links
Best practices:
- Test your QR code with multiple devices before distribution
- Provide a fallback URL for users who can't scan the code
- For print materials, ensure sufficient size (minimum 2x2 cm)
- Use high contrast colors (black on white works best)
- Add a call-to-action near the QR code ("Scan me!")
- Consider adding your logo to branded QR codes
