Closed System Fuels Fraud Defense
American Express, the New York‑based card network, reports its fraud rate remains among the lowest in the industry. It attributes this edge to a closed‑loop system that limits data exposure and leverages extensive cardholder and merchant information. This advantage stems from its proprietary platform that aggregates transaction details across its network, enabling real‑time monitoring and rapid detection of suspicious activity.
