Device, velocity, and funding-source consistency beat identity checks alone.
First-party fraud is hard precisely because the identity is real. The signals that work in production:
- Device and session consistency across the lifecycle
- Velocity and structuring patterns on funding events
- Funding-source mismatches versus stated intent
Identity verification alone won't catch it — you need behavioral scoring layered on top.
