TERMINOLOGY

When identification and recognition of humans are based on their physical attributes, it is referred to as biometrics. A biometric sensor is an identification and authentication device. These devices use automated methods of verifying or recognizing the identity, of a living person, based on a physical attribute. These attributes include fingerprints, facial images, iris and voice recognition.

Our “off-chip” capacitive fingerprint sensing technology separates the fingerprint sensing elements from the chip that process information it collects. This leads to high-quality fingerprint imaging, optimized biometric performance and outstanding user experience. It also allows users to record their fingerprint at many different angles – so the card can always recognize the user no matter how they hold the sensor.

In biometrics, FRR, or false rejection rate, is the instance of a security system failing to verify or identify an authorized person.

In biometrics, FAR, or false acceptance rate, is the measure of the likelihood that the biometric security system will incorrectly accept an access attempt by an unauthorized user. A system's FAR typically is stated as the ratio of the number of false acceptances divided by the number of identification attempts.
