The Risk Management service consists of a range of automated and configurable checks that are applied to credit cards , German ELV and Direct Debit payment attempts . These checks are supplementary to the standard checks Worldpay has incorporated into its payment service and help reduce the risk of chargebacks from credit card companies or banks.
The principle of risk assessment with the Risk Management service is as follows. All payment attempts are subjected to a number of risk screening checks. Each check assigns a value, called the risk score, to payment attempts that trigger that particular check. The sum of the risk scores indicates the likeliness of a fraudulent payment. If a payment attempt obtains a total risk score equal to, or larger than, the predefined risk score limit of 100, it is automatically refused before being sent to the acquirer for authorisation.
For merchants who offer credit card payment methods with Card Validation (CVC/CVV) or Address Verification (AVS) additional checks can be applied on the CVC/CVV and AVS response from the acquirer after the payment has been authorised. If one of these post-authorisation checks is triggered, its risk score is added to the existing total risk score of the payment. Authorised payments with a total risk score equal to, or larger than, a predefined risk score limit of 100 will automatically be cancelled. For more information, refer to the Risk Management service guide.
The Risk Management page allows for adjusting the risk score per check and, if applicable, a number of check parameters. An on-line description of the available checks and how to configure checks is available in the interface.
