Exchange Configuration

System Management > Exchange Configuration

Business rules are configurable settings which provide issuers control over the customer process during the 3-D Secure transactions. The Amount Threshold rule is used to determine whether authentication can be bypassed based on an amount threshold. To cater for this requirement, it is necessary to set a threshold amount in a default currency. Where the default currency is the same as the transaction currency, this calculation is straightforward. However, where these currencies differ, it is necessary to first convert the transaction currency to an equivalent value in the default currency before calculating whether the threshold has been exceeded. In order to compare the default currency and transaction currency values where they differ, it is necessary to maintain a list of currency exchange rates.

To automate the maintenance of currency exchange values, the ACS system has been configured to automatically download an external currency exchange rate resource file. Where this list of rates is not comprehensive, and a transaction is received which is in a currency not found on the automated list, this section provides the necessary functionality to manually create currency exchange values.

The Exchange Configuration page shows a list of manually configured currency rates. The Base Currency signifies the transaction currency whilst the Target Currency signifies the currency of the issuer threshold as configured in the currency value on the Amount Threshold rule page. The Rate value is used as a multiplier, to convert an amount in the Base Currency to an equivalent amount in the Target Currency. Manual exchange rates can be edited by clicking on the Base Currency link.
