Essentially it’s the opendime version 2

Load sats onto an address, which is stored on the card with NFC+PIN

The you can hand the card to someone - and they can check the balance, accept the physical card as payment without waiting for transaction confirmation, and later sweep the sats into their own wallet.

But unlike the more expensive, single-use opendime (as dope and cyberpunk as those are), this has 10 “slots” so it can be reused after the first person sweeps the funds.
