WooCommerce Payments leverages a fraud prevention tool, Radar from our partnership with Stripe. This provides you with confidence that risky transactions, especially those from card cashers and testers, will be blocked using machine learning capabilities trained across billions of dollars worth of transactions.
Radar’s functionality provides real-time fraud detection on every payment coming through your site and will block payments if necessary before they are charged. You can learn more about how Radar blocks payments here.
As WooCommerce Payments continues to enhance its platform, we will be looking to add more fraud detection functionality for our merchants. We appreciate your feedback if you’d like to submit on our ideas board.
