What is DCC?
The DCC application is a payment solution that allows foreign card holders from different countries of the world to make payments in their local currency. While this makes it easier to understand the price you are paying—and lets you avoid doing the currency conversion math—the service often comes with a poor exchange rate and other fees that can make the transaction more expensive than if you simply made it in local currency in the first place.
