When paying at pick-up, you'll have to pay in the local currency of the country where the car rental desk is located. Exchange rates fluctuate daily, so the amount you’re charged on the day you pick up the car might be slightly different than the one listed on your voucher. If you pay using a credit card denominated in a different currency than the one in the country where you pick up the car, you may be charged a currency conversion fee by your bank.
In a few countries where exchange rates are particularly volatile, your booking will be shown in EUR or USD, and you’ll be charged in the local currency at the current exchange rate on the day you pick up the car.
