Exchange online. Before attempting to exchange money online, be sure to check the exchange rates, as they change daily (oanda.com is a good site). Exchange rates specify the amount $1 (for example) translates to in another country's currency. Wells Fargo Bank owns foreignexchangeservices.com, where currency can be exchanged. Currency exchange websites charge a fee for these services, along with a shipping charge (Wells Fargo charges $8 for shipping).
Exchange at airports. Airports that have international flights usually have a currency exchange kiosk available for travelers leaving and coming back from other countries. Like online exchange services, these kiosks charge a hefty fee for exchanges. However, this is a convenient option when time is an issue and you do not want to go out of your way to exchange foreign money.
Exchange at banks. Many larger banks will offer currency exchange services. Be sure to call ahead of time to make sure that this service is offered. Be sure to go during open hours--most banks do not stay open past 6 p.m. For those that work, this may be a more inconvenient option, but the rates should be fairly reasonable and banks are usually, for the most part, trustworthy institutions.
Look for currency kiosks. Once you get to another foreign country, there may be currency exchange kiosks available at a variety of spots known for heavy tourist traffic or popular shopping locations. These also usually have very high fees for exchanges, and there may be a line during busy tourist seasons or holidays.
Use an ATM. In some countries, you may be able to use your credit card at an ATM and receive foreign currency. Be sure that your credit card company knows that you are traveling out of the country so your account does not get flagged for fraudulent activity if you do not go out of the country much. If you use an ATM, you may be facing a charge from the ATM itself and from the credit card company. Be sure you know these charges ahead of time.
