Here is a close-up demo of the nfc payment. Still lots of dev cruft in the UI but bear with me.
The wallet holder presses Pay with NFC, the payer taps their card (not shown). The payment amount and card data is sent for processing. The wallet returns to home screen and the payment comes in 3-4 seconds later.
Behind the scenes, the wallet generates the invoice and forwards this to the card vault, along with the payment card data. The vault decrypts the card data, and issues the payment instruction via NWC.
The NWC listens for incoming payment instructions and handles them, like paying an invoice.
Meanwhile the receiving wallet is listening for the paid invoice and once paid, stores the resulting cashu tokens, updates its balance and indicates payment.
All this and final settlement of tap to pay payment in about 3 seconds.
