@atomicpoet @cendawanita I used travelers checks on one trip many years ago. These days I’d like to load up a digital wallet with whatever crypto is used at my destination and just use that. No exchange fees or conversions needed. I’ve gone to festivals where you can only get food and drinks using the tickets you buy from the organizers. It would be sort of like that, but a digital currency. I’ve read of this sort of system being created already but have never seen it in use.

@atomicpoet @cendawanita @brennansv Most banks in Europe give you a card that works both as a credit card and as the common debit & prepaid card standard (Bancomat). The credit side is also associated with your bank account, so it's usually covered automatically at the end of the month unless this would result in an overdraw.
