Every card payment that you accept from your customers goes through a variety of transaction monitoring checks that are powered by our partner - Kount . Kount is one of the market leaders in the field of fraud detection, and is used by a number of digital businesses, acquiring banks, and payment service providers.
You can see the level of risk for every transaction by clicking on a particular payment in the Merchant Transaction list and expanding the transaction details.
Revolut also supports 3D-Secure authentication for card payments. If your customer checks out a purchase using 3D-Secure, the fraud liability shifts to the issuing bank - which means you will not incur any losses in that case.
