Dynamic Currency Conversion (DCC) is a service for credit cards that allows the cardholder to make a POS credit card purchase in a foreign country using the currency of their home country. DCC is an optional one-time service that the merchant may present to the cardholder to allow them to see the purchase price in their home currency. If the customer agrees to use the service, they also agree to additional service fees for the service.  DCC is only offered for in-person credit transactions.

This is supported on CreditAuth, CreditSale, CreditReturn, CreditTxnEdit, CreditAddToBatch, CreditReversal and CreditVoid request transactions.

A cardholder cannot change their DCC preferences between the original authorization and any subsequent secondary transaction.  The card used for the original DCC authorization must be the same card used for any subsequent transaction, such as CreditReturn.

If the original transaction contains the CurrencyConversion data block, then any CreditReturn must also contain that data block.

• Please note that GatewayTxnId is required for returns containing the CurrencyConversion data block

Use of this service requires a merchant to enter into an agreement with a Dynamic Currency Conversion processor, integrate to support the POS functionality, and support the Dynamic Currency data elements in transaction request messages.  There are no DCC-specific fields in the Portico response object.  See  CurrencyConversion. 

Dynamic Currency Conversion is available for merchants in the Restaurant, Retail and Lodging industries.

Integration to this service is not available for Direct-to-Portico integrations.  Merchants using this service must use Global Payments' Unified Commerce Platform.
