I have been looking into how feasible it could be doing so on iOS since my office door opens via an NFC card, but iirc Apple has a tighter grip on the NFC hardware than with general PassKit, meaning that a regular app can't do that.
- jackson1442 3y agoKinda. NFC is a broad spectrum of protocols. For example the old blue Orca cards are MiFare DESFire cards which actually store the card’s value in the card’s internal chip- this type (while having some flaws) cannot easily be copied onto a phone. A simple NFC tag with binary data is trivial to copy though.
