In this talk from an H2O.ai event, Karamjit Singh, Director of AI Products at Mastercard, walks through how AI is applied across the payments industry. He covers fraud detection, including third-party fraud like account takeover and synthetic identity, and first-party fraud like friendly fraud and chargebacks, how Mastercard's Decision Intelligence, Safety Net, and account-level scoring products assess risk in real time, and how AI is used to optimize transaction processing speed, customer experience, and interchange fee routing.
