The percentage of validation attempts in a biometric system that is either Falsely Accepted or Falsely Rejected where the probability of acceptance and rejection are equal. EER is a trade-off or a ratio between FAR and FRR. The false acceptance rate is allowing unrecognized/unwanted customers to log in and False rejection rate is rejecting previously validated users or preventing valid customers from entering the system. Customers can choose to fix their ratio in favor of any one of them. It KSV team will configure the system to suit customer needs and also monitor this.
