Complete Fraud Prevention Pipeline
Case

End-to-end fraud prevention pipeline for vehicles rentals

To ensure security from the very first user interaction, a mobility company implemented QI Tech solutions across onboarding and contract signing.

During registration, OCR with validation against the government CNH database, Liveness Detection, and antifraud analysis with customized rules and risk scoring are used. During formalization, QI Sign applies 1:1 facial validation (Face Match), a new liveness check, and Device Scan to confirm identity and detect signs of device fraud.

The result is a secure, frictionless digital journey with guaranteed legal validity.
