Credit cards are welcomed by most large businesses, so you probably won't have to use cash for payment in high-end hotels and restaurants. Many businesses on the other end of the spectrum don't accept them, however. It's a good idea to check in advance if you're staying in a budget lodging or eating in a simple country inn.

Prices are given for adults. Substantially reduced fees are almost always available for children, students, and senior citizens.

Banks almost never have every foreign currency on hand, and it may take as long as a week to order. If you're planning to exchange funds before leaving home, don't wait until the last minute.

ATMs and Banks

Twenty-four-hour ATMs (Geldautomaten) can be accessed with Plus or Cirrus credit and banking cards. Your own bank will probably charge a fee for using ATMs abroad, and most German banks exact €3–€5 fees for use of their ATMs when using cards not issued by them. Nevertheless, you'll usually get a better rate of exchange via an ATM than you will at a currency-exchange office or even when changing money in a bank. And extracting funds as you need them is a safer option than carrying around a large amount of cash. Since some ATM keypads show no letters, know the numeric equivalent of your PIN. Always use ATMs inside the bank.

PINs with more than four digits are not recognized at ATMs in many countries. If yours has five or more, remember to change it before you leave.

Credit Cards

All major U.S. credit cards are accepted in Germany. The most frequently used are MasterCard and Visa. American Express is used less frequently, and Diners Club even less. Since the credit-card companies demand fairly substantial fees, some businesses will not accept credit cards for small purchases. Cheaper restaurants and lodgings often do not accept credit cards.

It's a good idea to inform your credit-card company before you travel, especially if you're going abroad and don't travel internationally very often. 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.

If you plan to use your credit card for cash advances, you'll need to apply for a PIN at least two weeks before your trip. Although it's usually cheaper (and safer) to use a credit card abroad for large purchases (so you can cancel payments or be reimbursed if there's a problem), note that some credit-card companies and the banks that issue them add substantial percentages to all foreign transactions, whether they're in a foreign currency or not. Check on these fees before leaving home, so there won't be any surprises when you get the bill.

Before you charge something, ask the merchant whether he or she plans to do a dynamic currency conversion (DCC). In such a transaction the credit-card processor (shop, restaurant, or hotel, not Visa or MasterCard) converts the currency and charges you in dollars. In most cases you'll pay the merchant a 3% fee for this service in addition to any credit-card company and issuing-bank foreign-transaction surcharges.

Dynamic currency conversion programs are becoming increasingly widespread. Merchants who participate in them are supposed to ask whether you want to be charged in dollars or the local currency, but they don't always do so. And even if they do offer you a choice, they may well avoid mentioning the additional surcharges. The good news is that you do have a choice. And if this practice really gets your goat, you can avoid it entirely thanks to American Express; with its cards, DCC simply isn't an option.

Currency and Exchange

Germany shares a common currency, the euro (€), with 16 other countries: Austria, Belgium, Cyprus, Estonia, Finland, France, Greece, Ireland, Italy, Luxembourg, Malta, the Netherlands, Portugal, Slovakia, Slovenia, and Spain. The euro is divided into 100 cents. There are bills of 5, 10, 20, 50, 100, and 500 euros and coins of €1 and €2, and 1, 2, 5, 10, 20, and 50 cents. Many businesses and restaurants do not accept €200 and €500 notes. It is not possible to pay for anything in U.S. dollars, but you should have no problem exchanging currency. The large number of banks and exchange services means that you can shop around for the best rate, if you're so inclined. But the cheapest and easiest way to go is using your ATM card.

At this writing, the exchange rate was €0.75 for a U.S. dollar. But the exchange rate changes daily.

Even if a currency-exchange booth has a sign promising no commission, rest assured that there's some kind of huge, hidden fee. (Oh . . . that's right. The sign didn't say no fee.) And as for rates, you're almost always better off getting foreign currency at an ATM or exchanging money at a bank.

Exchange Rates

There are a number of handy websites that can help you find out how much your money is worth. Google does currency conversion; just type in the amount and how you want it converted (e.g., "100 dollars in euros"), and voilà. Onada allows you to print out a handy table with the current day's conversion rates. XE also does currency conversion.
