We detected signals that correlate with fraud risk.
See how this is calculatedDevice-level truth for every payment, account reset, and chargeback dispute.
Stop fraud Radar can't see — before the chargeback hits.
Stripe Radar's rules engine is world-class — but rules can only catch what they're written for. Fingerprint's device identity catches the patterns rules can't articulate: same attacker across new cards, fresh accounts, and rotated VPNs. The device persists when the transaction data doesn't.

Identify returning web and mobile app visitors on all browsers, iOS, and Android, with exceptional accuracy.
Get details on suspicious visitors even when VPN, incognito mode, or a tampered browser or device is used.

Personalize user experience and reduce 2FA and OTP requirements by identifying logged-out users.
Fingerprint gives Trust & Safety the device-level signal to flag fraud in flight — checkout, dispute lifecycle, and Sigma queries.
See all Case StudiesFingerprint provides clear device-level signals we can use to prevent fraud and reduce losses, while also enabling smoother customer journeys. It acts as fraud detector and a trust enabler. Leading financial services teams apply the same device intelligence philosophy — treating every interaction as a device event, not just a session.
