How AmEx used its credit fraud AI to start a banking product

When credit card giant American Express began offering bank accounts for the first time last year, it had a foundation of fraud detection to bring to an entirely new product arena. That meant in some cases, the company could port over AI and machine-learning models used to spot phony identities or dodgy transactions for its credit card products to its consumer and business checking accounts. But it's been a process, and now, AmEx plans to invest in bringing additional AI techniques used to protect against credit card fraud to its banking products. "We have models which run to detect whether it's you or whether somebody else is logging into your account. Very straightforwardly, we transferred it to the banking product," said Abhinav Jain, vice president for Global Fraud Decision Science at AmEx, who is responsible for the company's fraud detection models.
