Machine-learning card fraud scoring and AI-assisted contact centres

Bank of Ireland said AI assessed about one billion card transactions in 2025 and prevented €9.7 million in potential losses

WorkingCompany's own claimOfficial ↗

Problem

The bank needed to detect card fraud while payments were in progress, across more transactions than staff could check by hand. Customers also spent time being transferred between contact-center departments.

Approach

The bank’s AI and machine-learning system scored each card transaction for fraud risk. The score determined whether a payment could proceed or needed extra verification. A team of 225 staff worked on fraud and financial crime. Separately, contact-center AI routed customers to the appropriate help and assisted staff with call analysis.

Results

~1 billioncard transactions assessed by AI for fraud in 2025, per the bankCompany's own claim[1]
€9.7 millionpotential customer losses prevented in 2025, per the bankCompany's own claim[1]
-40%reduction in contact-centre call transfers from AI-powered support, per the bankCompany's own claim[2]

Takeaway

Fraud scores guided decisions to approve payments or require extra verification at a scale staff could not review manually. The bank’s €9.7 million figure estimated potential customer losses prevented, rather than realized savings.
