Add NFC api for magical web3 onboarding experience

[CalvinMaighan]

This is more of a feature request, but it would be nice if my TWAs had access to the native NFC api (on iPhone) so that I could invite a friend to my TWA and then tap their phone to give them some crypto to start playing my game.

Hope it can be supported at the app level and open web js sdk
