There are digital forms of currency already but barring that, you can still manage centralized trust with distributed communication.
Ie: maybe I trust a mechanism by Google/Apple where tap becomes powered locally and the phone/device itself carries a balance.
It’s true that these solutions don’t exist today but they are not far away with the amount of pressure we are talking about by losing the internet.
Also, credit cards used to work in a similar way to checks. The information would be recorded and the transaction would be finalized later.
I came across a pre-magnetic-strip credit card years ago… it’s pretty fascinating how currency has evolved in the last half-century. There is no reason for me to think that it will stop where we are at today.

That's something I'd definitely love to see, but it doesn't exist at the moment (in the US, at least; in Japan, there are stored-value cards in Apple Wallet that can support two-side offline transactions).

They used to, but they don't anymore. Almost all terminals and many cards won't let you do an offline transaction these days, for both credit and debit cards.

True, but unfortunately as far as I can see, it's all been moving towards a more centralized/connection-dependent system. That's great for when everything is working as expected, but raises some concerns about resilience.
