Credit Cards

It's a good idea to inform your credit-card company before you travel. Otherwise, the credit-card company might put a hold on your card owing to unusual activity—not a good thing halfway through your trip. Record all your credit-card numbers—as well as the phone numbers to call if your cards are lost or stolen—in a safe place, so you're prepared should something go wrong. Both MasterCard and Visa have general numbers you can call (collect if you're abroad) if your card is lost, but you're better off calling the number of your issuing bank, since MasterCard and Visa usually just transfer you to your bank; your bank's number is usually printed on your card.
