Fingerprint check to reduce check fraud

摘要

A digital image of a surface of a check is received. A check scanning device captures the digital image as the check moves through the check scanning device. A fingerprint is impressed on the surface of the check. A computing system uses the digital image to determine a match score. The match score represents an approximate probability that the fingerprint on the check matches a reference fingerprint. An alert is presented based on the match score.
