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 ?

I like the idea, though I had to look into the technical Workflow and test it to really get an opinion. But why 4210?

I love the concept, I’m looking into something very similar to be used as rewards system for a coffee shop. Each customer that buys the nfc card gets sats for every purchase. How you got the nfc in a pin, I’d like to make one that can go in a keychain.

This is awesome, definately could have usage. Reminds me of a poker chip w sats

I could see this with an e ink screen on top that shows the total amount of sats, but might be hard to implement

Good idea. I would try to make it thin as you could otherwise. Once 'spent' you could recycle the material if done right.

Good news! i tried to scam the coin i used a lightning wallet and read the nfc chip which would give me option to receive the amount on the chip, i didnt hit receive button immediately i could now spent the coin, and would hit receive later BUT as soon someone scans the coin for balance my claim ge...

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!
