You can make free withdrawals in all countries of the Euro zone for free, as long as a Visa logo can be seen at the ATM (which is usually the case).
The foreign currency fee for withdrawals that are not made in Euro is 1.5% of the withdrawal. Here you can see the current price list. For payments in foreign currency we follow the VISA exchange rate.
If you opened your account before our switch to Visa, you will of course need to look out for ATMs with the Mastercard symbol.
