Aight, is there going to be like, a message from their bank telling them their account's frozen? Or would it be more like, they go and try to buy something with their card and realize that, oh shit, their card's getting denied?

Also, is cash still a thing in this world, or is currency all digital?

Their account/credit card balance should be showing as zero, regardless of how much money they try to charge/transfer to it. So it's not like their accounts are frozen but rather like they have been picked clean and someone left a bottomless pit in their place.

There's still physical currency, but it's rare for people to have large sums of it, even more than today since automated payment methods should be the rule rather than the exception, like... Japan of today.
