What the person sees when they scan it
The QR code opens WhatsApp directly in a chat with the given number. If a message was filled in, it's already typed in the text field — the person just needs to review it and hit send.
Works even without the number saved

- What happens when someone scans this QR code?
- WhatsApp opens directly in a chat with the given number, with the message already filled in (if you added one) — they just need to tap send.
- Do they need the number saved in their contacts?
- No. The QR code uses a wa.me link, which opens the chat even if the number isn't saved.
- Does it work for numbers from any country?
- Yes, as long as you enter the correct country code (e.g. 55 for Brazil) together with the number, with no extra spaces or symbols.
