Definition
Dynamic Currency Conversion (DCC) is a service offered by a merchant to allow the cardholder to make the payment in the currency of his card instead of the currency of the merchant when different.

Processing
When DCC is allowed by the merchant, the cardholder can choose whether to accept the DCC service or not.
If the DCC service is accepted by the cardholder, the currency conversion is managed through a DCC service provider proposing to the cardholder the converted amount to be ultimately debited on his card.
If the DCC service is refused by the cardholder, the transaction then proceeds as a normal card payment transaction in the currency of the merchant.
Currency conversion during the authorisation | Not supported currently |
