Depending on the policies and features of your credit card, you may pay a fee for the currency conversion. Credit card networks charge the fee to your bank and the cost is generally added to your purchase. Some credit card issuers will pay the currency conversion fee for you, so you may want to shop around for a new credit card before your trip.
There’s another fee to look out for as well: the foreign transaction fee on purchases. The fee can be up to 3% of each purchase. That can add up.
Here is the TIP: If you could shop around ahead of time for a new card that offers a low foreign transaction fee (1%, for example) plus cash back rewards, you could potentially come out ahead.
