Private. Instant. Beep, done.\n\nIn the video: two Cashu wallets for bitcoin.\n\nLeft: Minibits (PoS)\nRight: cashu.me (payer)\n\nEcash is sent directly via NFC — no internet, no delay. Beep, boop.\n\nEcash is a bearer token — the money lives on your device, not on a server. That’s why it pairs so well with NFC. Pick an amount, tap to send. No talking to servers. No syncing. Just push it over. The payment is pretty much instant. A PoS can accept ecash from any mint and receive payments via Lightning.\n\nStill early days, but we’re experimenting. Card-to-phone works, but phone-to-phone? That’s the real killer use case.\n\nApple famously locks down the iPhone’s NFC chip — good monopolist.\n\nF*k that. I found a workaround.\nAs long as one phone (ideally the PoS) is Android, you can send data both ways between iPhone and Android.\n\n(You don’t really own your iPhone.)\n\nPeace!\n
