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.
Qualcomm ultrasonic fingerprint sensor

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.
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.
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.
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.
We’ve launched our most advanced 5g platform—ever. The Snapdragon 865 5G Mobile Platform is capable of processing 2 gigapixels per second while delivering staggering speeds of up to 7.5Gbps 5G connectivity to flagship mobile devices.
With the Snapdragon 865 5G, OEMs can elevate the camera experience thanks to the ability to capture a billion shades of color at gigapixel speeds—ensuring the mobile device is the only camera they’ll ever need. And with all-day battery life, users can game, capture, multitask, and connect like never before.
