Case Study: KTC achieves more precise fraud detection with ACI Worldwide

KTC boosts fraud detection 1.5x with ACI Worldwide

Krungthai Card PCL (KTC), a major credit card provider in Thailand, faced the challenge of combating increasingly sophisticated fraud threats in real-time while reducing high rates of false positive alerts. To protect its customers without adding complexity or user friction, KTC partnered with vendor ACI Worldwide and leveraged its AI-powered payments intelligence and ACI Fraud Management solution.

ACI Worldwide implemented its multilayer AI platform, developing multiple machine learning models and a dynamic feature library within just two weeks. This solution significantly improved fraud detection, outpacing an 85% detection rate and delivering a precise 3:1 false positive ratio. The implementation also made KTC 1.5 times more effective at detecting cash-out scams, modernizing their fraud operations and improving customer experiences.
