Company-reportedContinuous decisioningThat handcrafted rules are the primary way to identify digital payment fraud.
Financial crime · Nordic banking operations
Executive brief
The transformation metric is investigator yield, not model accuracy in isolation; a lower false-positive queue changes how scarce human judgment is allocated.
AI value · False-positive alerts and true-positive detection
Company-reportedVendor case study reports 60% fewer false positives and 50% more true positives
Outcome figures originate from Danske executives and Teradata materials; independent Forbes reporting quotes the same executive, not a separate audit.
Before
Apply human-authored fraud rules to transactions. → Review up to 1,200 alerts per day, most of which are false positives.
After
Score millions of transactions in real time using learned patterns and latent features. → Investigate the smaller, higher-yield alert queue and decide customer or enforcement action.
Human boundary
The model prioritizes and scores; investigators determine whether activity is fraudulent and what action to take.
Why it matters
That handcrafted rules are the primary way to identify digital payment fraud.
This case is company-reported. Use it for the operating-model shift; do not treat the numbers as independently measured.

Work that left the path
Human role before
Investigators spent most capacity clearing rule-generated false positives.
Human role after
Investigators focus on higher-risk alerts, contribute domain knowledge to model development, and retain case decisions.
AI roleReal-time learned transaction-risk scoring that complements the existing rules engine.
Up to 1,200 false positives per day; 99.5% of investigated cases not fraud; about 40% fraud detection→Vendor case study reports 60% fewer false positives and 50% more true positives
