What is check fraud detection software?

Results reflect confirmed check fraud prevented by participating financial institutions from January 1 through June 30, 2026. Institutions may have been active for different portions of the reporting period.

Stop Suspicious Checks Earlier

Check fraud becomes more expensive and disruptive after an item posts. FraudSentry helps institutions review suspicious checks earlier by combining check-image analysis with transaction and account-level detection signals.

Teams receive a more focused set of suspicious items to investigate, helping them act before posting and applicable return deadlines.

Examine Check Images

Analyze check images for indicators associated with altered, counterfeit and forged items.

Identify Transaction Anomalies

Surface activity such as duplicate checks, serial-number irregularities and unusual check behavior.

Focus the Review Process

Help fraud teams concentrate their time on suspicious items requiring further investigation.

Check Fraud Does Not Arrive on a Predictable Schedule

Most institutions experience a mix of smaller, recurring attempts and occasional high-value events. During the first half of 2026, one participating institution prevented more than $3.45 million in confirmed check fraud during a single month.

The lesson is not that every institution will experience a multimillion-dollar month. It is that historical losses cannot reliably predict the size or timing of the next attempt. Effective controls need to be operational before that event arrives.
