(Dynamic Currency Conversion) enabled. This is useful when card and terminal
currencies are different. Worldnet support Currency Conversion Rate request, merchant application can request Conversion Rate for the card, then cardholder have to decide if he/she would like to use eDCC service, and after this appropriate request to the TPS will be sent. eDCC enabled XML transaction request should include additional tag - ‘FOREIGNCURRENCYINFORMATION’ with all required nested tags.
DCC transactions are allowed for the eDCC-enabled terminals only. DCC support for the terminal can be enabled or disabled by the Worldnet support team only. DCC is not available on multi-currency Terminals (see section 3.3).
