Phone call QR code
Scanning shows your number with a call button, so nobody has to type it.
Questions
- Does it call straight away?
- No. The phone shows the number first and the person taps Call.
- Which format should the number have?
- Use the international format with the country code (for example +49 30 1234567), so it works for visitors from abroad too.
- Where is it useful?
- Shop windows and doors, vans, “for sale” signs, posters and emergency contact labels.
