## The world’s fastest Ultrasonic In-Display Fingerprint Sensor.

Using sound waves to read a finger‘s valleys and ridges, the Qualcomm® 3D Sonic Gen 2 transmits an ultrasonic pulse against the finger. The 3D pulse reflection creates a detailed 64mm2 reproduction of the scanned fingerprint for quick and easy security performance.

Qualcomm 3D Sonic Gen 2 is a product of Qualcomm Technologies, Inc. and/or its subsidiaries.

## Benefits

### Sleek security solution

Integrating the 3D Sonic fingerprint reader behind a smartphone's display enables 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 image. The 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.

### 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, 3D sonic meets the highest security standards for mobile devices, rejecting imposter photographs and fake mold of your finger.

### High-performance

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