It made my morning 😇🤞🍇

Tap-to-pay with CashuBTC ecash — for bitcoin.

Fiat credit cards nailed the UX: fast, offline, works anywhere.
I always wanted that for Bitcoin.
Now it’s open-source. Private. Instant. Beep, done.

In the video: two Cashu wallets for bitcoin.

Left: MinibitsCash (nprofile…6tav) (PoS)
Right: cashu.me (payer)

Ecash is sent directly via NFC — no internet, no delay. Beep, boop.

Ecash 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.

Still early days, but we’re experimenting. Card-to-phone works, but phone-to-phone? That’s the real killer use case.

Apple famously locks down the iPhone’s NFC chip — good monopolist.

F*k that. I found a workaround.
As long as one phone (ideally the PoS) is Android, you can send data both ways between iPhone and Android.

(You don’t really own your iPhone.)

Peace!
