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.

Meanwhile, here in South Africa, our intrepid criminals are making their own simcards, by the bucketload..

For fun - Put that phrase in Google. "No chill in Mzanzi"

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...
