QR codes turn any URL into a scannable image. They are the fastest way to share links in the physical world — on business cards, flyers, menus, and product packaging.
What Can a QR Code Contain?
- URLs — Any website link
- WiFi credentials — SSID, password and security type for instant guest network access
- Contact details — vCard format with name, phone, email
- Text — Any plain text up to approximately 3KB
- Email and SMS — Pre-addressed emails or messages

QR Code Best Practices
- Test before printing — Always scan your QR code with multiple devices before mass printing.
- Add error correction — Use Level H (30% error correction) for physical materials that may get worn.
- Use high contrast — Dark code on light background for reliable scanning.
- Minimum size — At least 2cm x 2cm. Larger for materials viewed from distance.
