The Base Rate Fallacy [0] suggests there's often a lot more true negatives than true positives. In this case a true negative is ignoring a non-fraudulent transaction and a true-positive is catching a fraudulent transaction.

As someone who never engages in fraudulent transactions, if I were a DB customer I'd be much more concerned about the false-negative rate of such software.
