This is just a concept, and the question is if it makes better offline money then eCash would do !?

I printed a small chip with a NTAG 424 inside.

It functions like a boltcard.

If you need to verify the balance you can do when you know the lightning server URL:

You can withdraw the Sats later !

But normally you would just send the balance if the receiver got a phone.

But you could trade the coins for goods if no one got a phone.

But a lot of trust would be needed.

What du you think ?

Cool idea...feels like a physical Lightning bearer card. It’s not as trustless as eCash since you can’t verify the balance offline, but it’s more intuitive for real-world use. Great for semi-offline trades, just not full offline cash. Keep experimenting!
