Wow, that's interesting, I'm a big fan of card payments because tap to pay is super convenient (most places in Prague have card readers) but what annoys me is the Visa / MasterCard duopoly. Because this means that a fraction of every payment goes to an American company - it's not a competetive market so they have a sizeable profit margin. It's cool that you have a local alternative, I wish we had that too or at least more than 2 competitors to push profits down, so that card payments don't leak money out of the economy.
