A comprehensive fraud monitoring and prevention system is built into the payment gateway and managed within the Merchant Management System. It is used to protect merchants and minimise fraud by enabling them to set transaction frequency limits and card usage within a specific timeframe.
Payment transactions are reviewed for repeating patterns within a defined period of time. The check can be performed based on various sets of data such as number of transactions or value of transactions over a given time period.
There are two different responses that the gateway can present. A soft limit will notify the merchant by email that a threshold has been met; or a hard limit which will fail a transaction if the threshold is met.
