Overview
Elavon Europe’s Dynamic Currency Conversion (DCC) Service is developed using conversion from our Elavon host.
Online DCC sends a real-time online look-up inquiry message to Elavon to determine if the payment card is eligible for DCC. When a card is eligible, the response message includes the chosen currency, current exchange rate, and the applicable mark-up. The mark-up percentage may be the:
- Standard percentage mark-up, or
- Mark-up percentage over ECB.
Using this method, the PSP does not store a BIN file locally on the POS device. The BIN is managed by the Elavon host. This ensures that the correct DCC eligible currency is always sent back in the online lookup response message.
You benefit from not worrying about a device storing old or out of date exchange rates. The current rate will always be sent back in the look-up inquiry message response.
Process
Elavon will issue the key elements and specifications required for you to develop for the DCC Service on POI solutions including the:
- Elavon DCC Integration Guide.
- Authorisation Protocol Specification.
- Settlement Protocol Specification.
Note: The Authorisation and Settlement protocol specifications outline the exact DCC messages format for sales, refunds, voids, pre-authorisation, etc., and the online inquiry request messages format.
Mandatory Capabilities
The DCC service must be supported and configurable at a TID level. The customer may have multiple TID’s associated to a MID and only want to support DCC on specific TIDs.
