timbo 🇩🇪 Yes, indeed. Both the Maestro and Mastercard have what bunq calls ZeroFX. You get billed in Euros according to the Mastercard exchange rate with no additional markup from bunq. And this is true for every type of plan.
Of course most non-Euro countries traditionally have a lower acceptance of Maestro cards, but probably especially on ATMs you have the ability to test this ;)
