What's the foreign transaction fee on my card?
Before using your credit card overseas to pay for purchases, you may want to find out how much that foreign transaction will cost you. Some credit card issuers charge a foreign transaction fee, typically between 2 percent and 3 percent of the purchase, to cover the costs of exchanging currencies. But other issuers absorb the cost of the currency conversion and charge you nothing. Bankrate's chart shows which credit cards don't charge these fees abroad and which ones do.
