This depends on the terminal. As far as I understand it, the terminal reads the card currency and if it doesn’t match the local currency, it offers to convert it for you.
For anyone who doesn’t know, dynamic currency conversion (DCC) is where the shop offers to convert the purchase into your local currency for you. Usually at a bad rate.
Of course, you should always be able to choose to be charged in local currency. Which you should, because then you get bunq ZeroFX 🌈
Is there something I’m missing that makes this a huge problem for Revolut and TransferWise cards?
Whenever I hit it while travelling, I just choose local currency and move on 😄
