Victor Emanuel Yes, you can use bunq cards to pay in any currency. Just make sure to enable the country in your card's settings. More info here: https://together.bunq.com/d/2815
And some advice: If there is ever an ATM or payment terminal that asks you to choose between currencies, always choose the currency of the country you're in currently. For example if you go to Poland and an ATM asks you if you want to pay for your withdrawal in Euro or in Zloty, you should choose Zloty. If you're in Brazil and a payment terminal asks you to choose between Euro or Real, then choose Real.
Why? Because it's much cheaper if you let bunq do the currency conversion instead of the merchant doing the conversion for you. More info on that: https://milelion.com/2015/04/24/beware-the-dynamic-currency-conversion-scam/
