Maybe I'm just retarded but I feel like there is not enough context to understand what is happening here.
Experimental merchant PoS app that is able to request ecash from Satocash smartcards.
In the video you see:
1) (merchant) inputs the amount in sats
2) scan the card + insert pin
3) receive ecash and generate a new cashu token that can be imported into your wallet of choice
4) (Hidden) the change is automagically re-imported into the card.
