If you are a frequent traveller, technology has made things easier for you. Now you need not carry a lot of foreign currency as your credit card is doing the job of currency exchanger very efficiently.
However, technology can have loop holes which could burn a hole in your pocket. One such loop hole of international credit card usage is the Dynamic Currency Conversion or the Cardholder Preferred Currency service.
Dynamic Currency Conversion (DCC) also designated as Cardholder Preferred Currency (CPC) is a service provided by merchants (not network service providers like Visa or MasterCard) in some countries where you go on vacation or a business trip.

As a precautionary practice always check your receipt, and if you see anything involving your home currency in a country that doesn’t use your home currency, ask the merchant to recalculate the amount in the foreign local currency.
