How does Ecash work with bitcoin? Is it 1 sat = 1 Ecash?

Curious, don't mean to sound rude: Offline how? Both of the devices in this video are connected to WiFi? Or you're strictly talking about the string of text (token) being sent offline? Either way, the future looks hella exciting. Between this, atms, satcards... it's nice to see everyday people...

So cool

Does this work from Android to iOS? 🤔

I’ve been using wallet of satoshi for ever , it always had a NFC scan https://m.primal.net/PsXb.mov
