Flagship smartphones use Qualcomm 3D Sonic Sensors to deliver in-display fingerprint scanning that is fast and reliable  it can identify prints even when your fingers are wet.

Qualcomm 3D Sonic Sensors deliver a better user experience by using technological advances and acoustics (ultrasonic waves) to scan 3D features such as ridges, valleys, as well as pores of a user’s finger for a deeply accurate image. This allows the Qualcomm 3D Sonic Sensor to scan fingerprints through solid surfaces like glass and metal even while wet. 

Qualcomm 3D Sonic Sensor is also ultra-thin, measuring a scant .2mm. This enables OEMs to build mobile devices with cutting-edge form factors. This includes full edge-to-edge flexible OLED displays. 

Qualcomm Technologies’ first generation of Qualcomm 3D Sonic Sensors were featured in many flagship smartphones including the Samsung Galaxy S10, Note10, S20, and Note20 series. 

Today, Qualcomm Technologies is introducing the Qualcomm 3D Sonic Sensor Gen 2. This second-generation sensor will be available in new sizes that are 50% faster and 77% larger compared to Gen 1.  

Qualcomm 3D Sonic Sensor Gen 1 was 4x9mm (surface area 36mm2). Gen 2 will debut with a sensor that is 8x8 (64mm2), which is 77% larger than Gen 1. 

The larger sensor provides a larger region for you to place your finger and allows Qualcomm 3D Sonic Sensor to capture 1.7x more biometric data. This larger sensor combined with faster processing will be 50% faster than Gen 1 so you can unlock your device quicker than ever. 

Qualcomm 3D Sonic Sensor Gen 2 are expected to debut in mobile devices in early 2021.
