Oddbean new post about login | logout Cashu NFC card merchant small demo: 1) Type in the requested amount. 2) Tap card to pay. https://m.primal.net/LEkK.mp4
MORE: the merchant is configured to accept direct ecash only if mint is recognized as trusted (there are trusted mints settings). If not, the merchant attempts to fetch an invoice from one of its trusted mints and pay it with the ecash provided in the card.
Imagine if having your credit card cloned would mean you only lose the money you have in it at that time. You don't have do freeze it, you don't have to get a new one. None of that hassle. nostr:nevent1qqsf7m2p032wtqj95ve6y5r0rq2wlrd7jpxnk7hznqnu3nxhvjj4wpgpy4mhxue69uhkvet9v3ejumn0wd68ytnzv9hxgtm0d4hxjh6lwejkuar4wfjhxq3qu07xw079lxwv24xslarh2eu4v37jtjmwvev0jyk3zjhxg2wnt56sxpqqqqqqzcl2q5p
This is absolutely incredible. How many bytes are required to hold ecash on an nfc tag?
