ATMs
The Cirrus (tel. 800/424-7787; www.mastercard.com) and PLUS (tel. 800/843-7587; www.visa.com) automated teller machine networks span the globe; look at the back of your bank card to see which network you're on, then call or check online for ATM locations at your destination. Be sure you know your personal identification number (PIN) before you leave home and find out your daily withdrawal limit before you depart. Keep in mind that many banks impose a fee every time you use their card at a different bank's ATM, and that fee can be higher for international transactions (up to $5 or more) than for domestic ones. On top of this, the bank from which you withdraw cash may charge its own fee. To compare banks' ATM fees within the U.S., use www.bankrate.com. For international withdrawal fees, ask your bank.
You can also get cash advances on your credit card at an ATM. Keep in mind that credit card companies try to protect themselves from theft by limiting the funds people can withdraw outside their home country, so call your credit card company before you leave home. And keep in mind that you'll pay interest from the moment of your withdrawal, even if you pay your monthly bills on time.
Traveler's Checks
Traveler's checks are something of an anachronism from the days before the ATM made cash accessible at any time. Keep in mind, however, that you will likely be charged an ATM withdrawal fee if the bank is not your own, so if you're withdrawing money every day, you might be better off with traveler's checks -- provided that you don't mind showing identification every time you want to cash one.
You can get traveler's checks at almost any bank. American Express offers denominations of $20, $50, $100, $500, and (for cardholders only) $1,000. You'll pay a service charge ranging from 1% to 4%. You can also get American Express traveler's checks over the phone by calling tel. 800/221-7282; Amex gold and platinum cardholders who use this number are exempt from the 1% fee.
Visa offers traveler's checks at Citibank locations nationwide, as well as at several other banks. The service charge ranges between 1.5% and 2%; checks come in denominations of $20, $50, $100, $500, and $1,000. Call tel. 800/732-1322 for information. AAA members can obtain Visa checks for a $9.95 fee (for checks up to $1,500) at most AAA offices or by calling tel. 866/339-3378. MasterCard also offers traveler's checks. Call tel. 800/223-9920 for a location near you.
Foreign currency traveler's checks are useful if you're traveling to one country, or to the euro zone; they're accepted at locations such as bed-and-breakfasts where dollar checks may not be, and they minimize the amount of math you have to do at your destination. American Express, Thomas Cook, Visa, and MasterCard offer foreign currency traveler's checks. You'll pay the rate of exchange at the time of your purchase (so it's a good idea to monitor the rate before you take the plunge), and most companies charge a transaction fee per order (and a shipping fee if you order online).
If you choose to carry traveler's checks, be sure to keep a record of their serial numbers separate from your checks in the event that they are stolen or lost. You'll get a refund faster if you know the numbers.
Credit Cards
Credit cards are a safe way to carry money: They also provide a convenient record of all your expenses, and they generally offer relatively good exchange rates. You can also withdraw cash advances from your credit cards at banks or ATMs, provided you know your PIN. If you've forgotten yours, or didn't even know you had one, call the number on the back of your credit card and ask the bank to send it to you. It may take 5 to 7 business days.
Some companies ask that you notify them of an impending trip so they don't suspect fraud and block your charges. If you skip this step, carry the card's toll-free emergency number with you, separate from your card, so you can call if a charge is refused. Most importantly, carry more than one card; one might not work for any number of reasons, so it's best to have a backup.
