 Just had a thought... what if your cashu ecash was on a physical device like this that used nwc or another secure method over nostr to make a payment?

Yeah, it's like client-server architecture, but both client and server is yours and heck, it makes your ecash physical, not individually, but like an ecash vault.

Even if we gotta trust a mint, we can still secure the cash. 🤷 
 @calle 👁️⚡👁️ this is where you tell me someone is already working on this too. 
 I would love to see this, maybe on an esp32-style cheap device.
