HOME / FAQs / FINGERPRINT SENSORS

What is a capacitive fingerprint sensor?

Capacitive fingerprint sensors generate an image by measuring the changes in capacitance between the ridges and valleys that make up the fingerprint. This contrasts with a traditional optical sensor which uses reflected light to build an image of the fingerprint.

We are one of only two suppliers to offer off-chip capacitive fingerprint sensors and the only supplier using this technology with the preferred ridge matching biometric algorithm. Our off-chip capacitive sensors separate the sensing elements from the silicon chip that makes the capacitance measurement to build an image of the fingerprint. This ingenious design ensures excellent security, significantly higher image fidelity, superb noise immunity and market-leading usability under real-world conditions. You can find out more here.
