What is Fraud Screening?
Fraud screening is the real-time triage that determines whether a user or transaction should glide, get challenged, or be stopped. It combines rule checks (velocity, BIN/country corridors, mismatched AVS/CVV), statistical models, device intelligence, and behavior analytics. Done well, it’s silent—most legitimate customers will never know it’s there. Done poorly, it’s a hurdle that frustrates users, blocks revenue, and overwhelms support.
Inputs can include device fingerprints, network reputation, payment telemetry, historical disputes, graph edges to other accounts, and soft signals like geovelocity or time-on-page. The strategy converts those features into a decision with an explanation: approve, step-up, manual review, or decline. Tighten thresholds when risk is high (new device + new payee + large amount) and loosen them when risk is low for trusted cohorts. Watch the false decline rate—it’s an invisible leaky bucket.
