A URL QR code is the most common type. Keep the link short so the QR is less dense and easier to scan.
Best link practices
- Use a short, stable URL (avoid links that expire).
- Prefer your own domain or a clean landing page.
- Test on mobile data and Wi-Fi.
Print tips
- Use SVG for print; PNG is fine for screens.
- Keep a clear quiet zone around the code.
