Qualcomm 3D Sonic Sensor

3D Sonic: security that goes beyond screen deep.

Meet the world’s highest-performing, thinnest, most reliable fingerprint security solution. Qualcomm® 3D Sonic Sensors power the first ultrasonic fingerprint readers on mobile devices. As the premier, high-performance security solution that lives beneath a smartphone screen’s surface, they provide single-touch authentication using sound waves instead of light to recognize and safeguard users.

Qualcomm® 3D Sonic Sensor and Qualcomm Snapdragon are products of Qualcomm Technologies, Inc. and/or its subsidiaries.

Combining sleek design with anti-spoof protection in nearly any condition.

Providing our most cutting-edge, sleekest security solution.

Combining a smartphone’s display and fingerprint reader for a seamless and sleek look, 3D Sonic uses technological advances and acoustics (sonic waves) to scan the pores of a user’s finger for a deeply accurate 3D image. An ultra-thin (0.2 mm) sensor enables cutting-edge form factors such as full glass edge-to-edge displays, and can be widely used with flexible OLED displays.

Delivering security-rich, built-in anti-spoofing security.

Safeguard a user’s identity with the most advanced fingerprint security system available. 3D Sonic uses acoustic-based technology that reflects the unique features of a user’s individual fingerprint vs. optical solutions, which leaves users exposed to spoofing. With anti-spoofing built in, neither a photograph nor fake mold of your finger can access your phone.

Offering high-performance protection, even in extreme conditions.

3D Sonic delivers high-performance protection across a wide range of conditions—dry, wet, and even contaminant exposure—and it’s faster compared to legacy solutions when fingers are wet.

Achieving gold-standard safety with 3D sound.

Using sound waves to read a finger‘s valleys and ridges, our 3D Sonic Sensor transmits an ultrasonic pulse against the finger. This creates a detailed 3D reproduction of the scanned fingerprint for quick and easy security performance.

The Snapdragon 855 Mobile Platform offers fully secure, immersive 5G experiences.

The Snapdragon 855 Mobile Platform—the world’s first commercial 5G mobile platform—is designed to deliver multi-gigabit speed, extended reality (XR) experiences, on-device artificial intelligence (AI), 4K HDR video capture and playback, and so much more—including the ultimate security provided by 3D Sonic technology.
