My Flipper is now an ecash wallet. 😎
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.

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.
