Fraud Detection / Risk Assessment

Tools and models that score transactions or accounts to block or step-up risky activity.

POSE-Commerce

Fraud detection (risk assessment) evaluates transactions, accounts, or devices to spot abuse. Signals include device fingerprints, behavior, velocity, chargeback history, and identity data.

For cards, models can adjust friction by context: card-present vs. card-not-present, use of network tokenization, or wallets like Apple Pay and Google Pay. Strong risk controls reduce card fraud and chargebacks.
