I just returned from Ukraine and long story short I was unable to find ATM that would recognize the card.
I tried a very new one with fancy UI and touch controls (as some people anecdotally suggested out of date software) and it did not work.
“Invalid card” was the message on all of them. All my other cards were properly recognized and worked. That includes Santander, N26, TransferWise, bunq, Nordea and KBC.
Maybe it’s the time to do something about it? Also TransferWise had much better conversion rate than Revolut when paying at the terminal 3,99 vs 4,14 UAH.
