Kate is implementing biometrics in her company. Which of the following should be her biggest concern?

False acceptance rate (FAR) is the rate at which the system incorrectly allows in someone it should not. This is obviously a significant concern. Any error is a worry, but the false rejection rate is less troublesome than the false acceptance rate. The crossover error rate (CER) is when the FAR and the false rejection rate (FRR) become equal. This indicates a consistent operation of the biometric system. The equal error rate is another name for crossover error rate.
