When thinking about offline currency and simcards we identified the following:

verifiable centrally issued identifier printed on card and can be verified by inserting into any phone

coin-like small physical tokens

offline verification processes could be as simple as a distributed poster with whitelisted id's

distributed and decentralized bootstrapping based on trust in accepted id's.

As you know this is imho a cool idea. I'm thinking, what hinders the barista in usecase 1 from using the received simkojn in the cash register? Isn't some sort of removal of cards from the list necessary? Maybe I'm missing something...

simkojns are cash, reusable
