Dynamic currency conversion (DCC) is a feature that can be enabled on terminals, where a prompt will appear during a transaction to show the real-time exchange rate. This feature gives the customer the option to pay in either their home or local currency. More information on DCC can be found here.
Enabling DCC is free and serves as a convenience factor for international customers by giving them the ability to pay in their home currency. More information on DCC can be found here.
