Explanation:
Biometric performance is most commonly measured in two ways: False Rejection Rate
(FRR), and False Acceptance Rate (FAR). The FRR is the probability that you are not
authenticated to access your account. A strict definition states that the FRR is the
probability that a mated comparison (i.e. 2 biometric samples of the same finger)
incorrectly determines that there is no match.
