[Closed] Transmit the virtual card by NFC

Thanks for the idea. Unfortunately I had to close this one (at least for now), as it is technically not possible to use iPhone's NFC to transmit content. For third-party developers it is allowed to read and write to NFC tags/cards, but not to use the iPhone as a transmitter itself.
However, by using the iOS standard share sheet, you will be able to transmit your QR code cards content e.g. by AirDrop, Mail, Messages etc. This feature will be part of a future release.
