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.

นึกถึงแหวนพี่บี nostr:npub1p2c9e3c9r7y3cjwhv4f4g6s574r2xkvnvrkhp3lg3vudxl3mpu6s520r2c เลย
อนาคตคงเป็นแบบ เมียโยน ecash ใส่แหวนไปทำงานวันละ 50 sats งี้ แน่ ๆ 🤣

Amazing! This feels like a step forward for people less prone to use advanced tools, you can just pass the money over and the receiver will have to only verify the amount.
Even if this is a not a regular NFC card, I wonder how is the double-spend solved if you are offline?
Which phones are you using for this?
Two pixels
But it works with the most Android Phones, right?
And is this a special App?
Probably something similr to this: https://www.boltcard.org/
This is nice
Looks cool. Need to learn more about this
Only so much bandwidth in a day

https://smilemoji.cash to test this out. You'll need a regular NFC card or tag with at least 4Kb of storage.
Please DO NOT use smilemoji.cash as a real wallet because i will take it down once the PR is merged!
pretty neat. Also pretty useless for anything other than a giftorang pilling. In a transaction the receiving party would need a phone to verify anyway, and the card would be just another step.
Am I misunderstanding or is this putting a copy of the ecash token on the card?
I guess this is good if you arent physically meeting someone but can get them a physical card, avoid encrypt and send via email, or anonymous bearer instrument.
Receiver gets value, and can then reuse the card or keep as a collectible
Hi! You blocked me on X 😢 I saw this today, I guess it’s a fake you:

I think that twitter/x will now show posts from people that have blocked you but will (still) not let you interact with them.
wow I'm impressed!! is it enuts?
Can we play with it yet?
https://smilemoji.cash remember the demo i showed you?
Yes, but I didn't realize it was live and I could play with it!
Fuck yes!
Educate us please 🙏
Love it! As a nut maxi 🌰
I have built very similar project with LNUrl circa year ago…
My Flipper is now an ecash wallet. 😎
Dayum
I either came up with something unique or incredibly stupid, can't tell which. 😂
That is actually a really good idea. And you can type the amount and hand over just the ecash notes in that amount. And just mark them as spent locally. Much safer than dumb card which gives everything.
How does one make a flipper app?
A small gadget with brains + NFC has the potential to be a very cypherpunk ecash hardware wallet. Would love to see this in reality.
I'm new to it, but I don't think any dev-type-person would have any problem. They're called FAPs (😆) and they seem to run the code like an APK or something and reference data folders. Most of it gets stored on an SD card.
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 🤔
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.
Awesome 👏 can’t wait to try it
This is what we need

They'll never be able to keep up with our private cash 😂
I think this could be *so much* better with a smart Java card.
Question: Is it possible that a terminal could tell the card "Hey card, select 2500 sats and send them over"?
Prepaid card for the kids. Love it!
Woah 🤯
Algo parecido hicimos con las tarjetas #lightning de #lawallet de nostr:npub1rujdpkd8mwezrvpqd2rx2zphfaztqrtsfg6w3vdnljdghs2q8qrqtt9u68
Enviar sats ⚡ desde una tarjeta a otra
También un P2P o Arbolito como le llamamos en Argentina en dónde te da dinero Fiat y le cargas su tarjeta

Ok, anyone seen those credit card size calculators?
Imagine that, but there are no buttons, just a low voltage numeric display, slim internal battery, small solar strip, the nfc reader and you have a payment card which visually verifies how many sats it's holding 🤯 now that feels like scifi money!
Wow this is totally awesome! 😮⚡️🔥
