How much does it cost to use a credit and/or charge card when traveling outside the country?

On my first trip overseas, more a decade ago, I made a long list of things to do before I left home. First on that list, I called my credit card company to let them know I'd be traveling outside of England. If I didn't update them, I was worried I'd either get a call from them when I tried to make a purchase overseas, or worse, I might not be able to use my card at all.

To try to prevent fraud, credit card companies keep track of your usage patterns. So, if going to Europe isn't a regular occurrence for you, the company assumes someone else is using your card. "Credit cards are still the most effective way to buy foreign currency".
