only people who work at fintechs can tell you off the top if their bank card is visa or mastercard

the average consumer has no idea what card network their bank card is from

there is a lesson in that for founders obsessed over which chain to build on

I was in Panama yesterday and the shopkeeper said only Mastercard and I literally shrugged and handed my card to her and was like does this work?

that's odd. we have a version of this in South Africa where some merchants (usually in affluent areas) refuse to accept cash as a form of payment and only take card. at least they don't insist on a specific card network.
