Know before you start
- A QR code cannot confirm that a destination account or phone number exists.
- Low contrast, dense logos or very small printing can reduce scan reliability.
If the result is not right
- If scanning fails, remove the logo, increase contrast and use higher error correction.
- For WhatsApp, use a complete international number and confirm the account is registered.
