`Dynamic Currency Conversion` Payment Services {#dcc-intro}
===========================================================

When processing international transactions, `Dynamic Currency Conversion` (`DCC`) is a service that enables you to convert a transaction amount from a merchant's local currency to the cardholder's billing currency in real time. This service is regulated by Mastercard and Visa.  
The `DCC` service enables you to choose your own currency-conversion service provider for `DCC`. This setup helps you comply with Mastercard and Visa payment processing rules and other regulations for these transaction types.  
The currency conversion is performed directly between you and your `DCC` service provider before authorizing a network-compliant `DCC` transaction on your processor connection.  
These card types support `Dynamic Currency Conversion` transactions:

* Mastercard
* Visa
