Stop payment fraud before authorization
Link devices across cards and accounts, catch card testing and velocity abuse, and score risky checkouts in real time — without adding friction for good buyers.
The device is the constant fraudsters can't change
Card numbers, emails and shipping details are cheap to rotate. The device is far harder. A stable device fingerprint ties a card-testing ring together across thousands of attempts, and links a chargeback back to every other order from the same hardware.
Device linking
One device paying with many cards, or one card across many devices, is surfaced even when names and emails differ.
Velocity & spread
Transaction velocity per device and device-spread per account catch card-testing rings and mules.
Anonymized networks
VPN, proxy, Tor and residential-proxy detection flag the networks fraudsters check out from.
Behavioral biometrics
Unnatural form-fill and paste patterns separate a human buyer from an automated checkout script.
Score, don't just block
Prynt returns a suspect score and reason codes per checkout, so your risk engine can auto-approve trusted devices, step up borderline ones, and decline the obvious rings — keeping approval rates high while chargebacks fall. A confirmed-bad device on the reputation network is flagged the instant it returns.
