Some consider this the currency of the cave man, and it's true that fewer establishments accept traveler's checks these days. Nevertheless, they're a cheap and secure way to carry extra money, particularly on trips to urban areas. Both Citibank (under the Visa brand) and American Express issue traveler's checks in the United States, but Amex is better known and more widely accepted; you can also avoid hefty surcharges by cashing Amex checks at Amex offices. Whatever you do, keep track of all the serial numbers in case the checks are lost or stolen.
American Express now offers a stored-value card called a Travelers Cheque Card, which you can use wherever American Express credit cards are accepted, including ATMs. The card can carry a minimum of $300 and a maximum of $2,700, and it's a very safe way to carry your funds. Although you can get replacement funds in 24 hours if your card is lost or stolen, it doesn't really strike us as a very good deal. In addition to a high initial cost ($14.95 to set up the card, plus $5 each time you "reload"), you still have to pay a 2% fee for each purchase in a foreign currency (similar to that of any credit card). Further, each time you use the card in an ATM you pay a transaction fee of $2.50 on top of the 2% transaction fee for the conversion -- add it all up and it can be considerably more than you would pay when simply using your own ATM card. Regular traveler's checks are just as secure and cost less.
