Synaptics Announces Under-Glass, Button-Free Optical Fingerprint Sensor For Smartphones

Do you love the idea of a fingerprint sensor, but feel like the button that enables this functionality ruins your phone aesthetic? Synaptics has a solution for you. The San Jose, California-based corporation is releasing the FS9100, an optical fingerprint sensor that enables a button-free design.

According to Les Santiago, Research Director for IDC, “By bringing optical sensing technology with the right form factor and power consumption envelope to smartphones and tablets, Synaptics is enabling the elimination of the home button which is a critical next step to full top-to-bottom, edge-to-edge smartphone and tablet displays.”

Natural ID FS9100 optical fingerprint sensors feature Synaptics’ SentryPoint technology, which has a number of authentication features, including Quantum Matcher with PurePrint. PurePrint is able to examine fingerprint images and determine which ones are real and which ones are fake.

The sensors have been designed to be placed under cover glass, including 2.5D glass. It is capable of high-resolution scanning through up to 1 mm of full cover glass. The biometrics of the sensor get rid of button cut-outs and glass thinning processes required by capacitive under-glass sensors. The glass on the phone is therefore stronger, but thinner. Impressively, the sensor can even read wet fingerprints.

Several new products using Synaptics sensors have been released in the past year, including the TteSports Black V2 Gaming Mouse With IronVeil. The mouse not only ensures that a certain user logged in, but that he or she remains the player actually using the PC/mouse throughout the session.

The Natural ID FS9100 optical fingerprint sensors are scheduled to sample in the first quarter of 2017, and will be ready for mass production by the second quarter.
