This is amazing but I didn’t understand. The receiver didn’t specify an amount like you would do in a credit card payment. Is this just receive full amount stored in the card 🤔
Testing ecash payments with bearer tokens stored on a physical card. You can see the card being topped up with one phone and pay the other. It feels incredibly fast and smooth.
Tap to pay UX with ecash is as good as it gets for payments. You're literally handing over the money.

This isn't supposed to be a debit card.
It's an ecash note.
I think it's still a valid question and actually the biggest challenge in this current design. Either the card needs brains to do coin selection, or the receiver NFC reader must select the correct amounts it wants to withdraw.
