Real-Time Payment Fraud Decisioning

Detects and scores potentially fraudulent transactions across cards, deposits, merchant payments, and emerging payment rails in real time, enabling fast approval, decline, or step-up decisions that reduce fraud losses while minimizing friction for legitimate customers.

The Problem

“Real-Time Payment Fraud Detection and Decisioning”

Organizations face these key challenges:

1

Static rules miss novel fraud patterns and require constant manual tuning

2

High false-positive rates create customer friction and lost transaction revenue

3

Fraud signals are fragmented across channels, processors, and core systems

4

Decision latency budgets are tight, often under 50-150 ms end to end

Impact When Solved

Reduce fraud losses through real-time risk scoring before authorization or postingLower false positives and false declines to protect revenue and customer experienceUnify fraud controls across cards, ACH, RTP, wires, merchant payments, and walletsShorten analyst investigation time with explainable risk factors and case prioritization

The Shift

Before AI~85% Manual

Human Does

  • •Review flagged transactions and decide approve, decline, or hold
  • •Manually tune fraud rules and thresholds by payment channel
  • •Gather signals from processors, core systems, and case notes
  • •Prioritize investigations and escalate suspected fraud patterns

Automation

  • •Apply static rules to incoming transactions
  • •Trigger basic velocity and threshold alerts
  • •Route flagged payments into manual review queues
With AI~75% Automated

Human Does

  • •Approve fraud policies, step-up strategies, and risk tolerances
  • •Review high-risk or ambiguous transactions and make final exceptions
  • •Investigate prioritized cases and confirm fraud outcomes

AI Handles

  • •Score transactions in real time using cross-channel risk signals
  • •Execute approve, decline, or step-up actions within latency limits
  • •Prioritize alerts and explain key risk factors for analysts
  • •Monitor fraud patterns, false positives, and decision performance continuously

Operating Intelligence

How it works

AI runs the operating engine in real time.

Humans govern policy and overrides.
