Synaptics releases optical fingerprint sensors for smartphones


Synaptics has released a line of Natural ID biometric authentication solutions that leverage high-performance, highly secure optical-based fingerprint sensors for smartphones and tablets.

The new line of Synaptics FS9100 optical fingerprint sensors offer high-resolution scanning through 1mm of full cover glass and enables button-free industrial designs.

Natural ID FS9100 optical fingerprint sensors are designed to be placed under the cover glass, including 2.5D glass, located in the front, bottom bezel of devices.

Cover glass biometrics eliminates button cut-outs and glass thinning processes required by capacitive underglass sensors, leading to glass yield improvements.

The optical fingerprint sensor also delivers wet finger performance, while its glass-protected design makes the sensor highly durable, scratchproof, waterproof, and eliminates ESD issues.

Unlike other optical fingerprint sensors used for access control and public biometric identity verification, the FS9100 sensor is built using Synaptics optical technology developed for mobile devices and overcomes technical challenges with an extremely thin form factor and minimal power consumption.

FS9100 sensors feature Synaptics’ SentryPoint technology, providing OEMs with a wide selection of highly secure authentication features including Quantum Matcher with PurePrint anti-spoof technology.

In addition, Synaptics’ PurePrint anti-spoofing technology examines fingerprint images using unique artificial intelligence (AI) technology to differentiate between fake and real fingers.

“Synaptics’ FS9100 family of fingerprint sensors represent a new breed of optical fingerprint sensor technology that is designed to meet the needs of mobile devices, including the ability to image through thick 2.5D glass,” said Anthony Gioeli, vice president of marketing for Synaptics’ biometrics product division. “In addition to opening the door to new industrial design options, it enables OEMs to provide highly durable, button-free cover glass and more easily provide water resistant products while eliminating low yield glass processing.”

A demonstration video of FS9100 optical fingerprint sensors can be viewed here.

Previously reported, ASUS selected Synaptics‘ Natural ID fingerprint sensors for secure, high-performance biometric authentication on its flagship tablet, the ASUS Zenpad 3S 10.
