I get a lot of questions about foreign currency. People always ask 
me, "what's the best way to get money abroad? Will my credit card work 
overseas? Are travelers checks better than cash?" It's a confusing 
subject. So I thought I'd go straight to the source. I spoke with 
Melinda Mulcahy. she works in the traveler's check division at 
American Express. Now, I use travelers checks a lot when I travel, so 
I asked her if there are there any disadvantages.
Well, one person already educated is Conner Gorry; she travels all over Central and South America for the Lonely Planet guidebooks. I figured, if anybody can give me an on-the-scene report about what you need money-wise when you travel, it's her. So I asked Conner: out of credit cards, travelers checks, ATM cards, and cold, hard cash, what's does she find the most useful?
Now, even though ATMs are ubiquitous these days, I still tell people 
to take a little local currency whenever they travel. It's a good 
idea, in case you run into an ATM glich or the airport money changers 
are closed. And always check with your bank before you go. In some 
countries you need a special access code -- usually just an extra 
digit or two on your PIN. And one other thing is still true. When you 
pay with a credit card overseas, you usually get a better exchange 
rate than you would with cash. That's because your credit card 
company charges you the base conversion rate -- better than you'd get 
on the street, or even at a bank.
But what if you are off the beaten path like Conner and you do get 
stuck? See if you can get your friends in the U.S. give a call to the 
international money company Thomas Cook and Associates at 
800-287-7362.  For $35, they'll wire money anywhere around 
the world. And tell your friends not to worry...you'll pay them back 
when you find your way home.
