Explaining fraud alerts to reduce false declines
Cardholders abandon purchases after unexplained fraud blocks; analysts struggle to confirm edge cases quickly.
Problem
Rules and models flag unusual travel or merchant categories; customers cannot easily prove legitimacy in the moment.
Current workflow
Alerts queue to analysts; customers call contact centers; many transactions are declined first.
Consequences
Lost merchant sales and customer frustration.
How AI might help
Explainable scores and conversational step-up verification can confirm legitimate spend faster.
Limits & risks
Adversaries may probe explanations; need privacy-preserving designs.
Leaking decision logic; unfair treatment of certain merchant categories.
Alternatives today
Stricter rules or looser thresholds.
Stricter rules increase declines; looser rules increase fraud loss.
Evidence
