Frequently asked questions

What triggers fraud friction?

Velocity, geo mismatch, device fingerprint, amount anomalies, and merchant category signals.

How explain to user?

We need to verify this payment with plain next steps, not error codes alone.

Fraud vs return prediction?

Fraud flags abuse and theft. Return prediction forecasts product send-backs.

False positives?

Offer alternate verification and fast human review path.
