The Bargain Journal: Using a credit card in a foreign country

Using a credit card in a foreign country

Nice article on investopedia. Take away:

Use a card with little or no foreign transaction fees: E.g. that from a federal credit union (FCU). Applies only to certain FCUs though. (Please ask your bank).
Tell the bank in advance that you will be traveling to enable foreign transactions.
Sign receipts only in the local currency rates so that you will get the default competitive conversion rate.
Carry an ID (passport) for validation.
