CES 2021: Qualcomm unveils new fingerprint sensor 50% faster

Fingerprint readers positioned under the screen have become widespread in recent years. The advantage of this technology is to extend the display surface without enlarging the dimensions of the telephone. Unlike some manufacturers who rely on an optical system, Qualcomm has developed an ultrasonic sensor that therefore uses sound waves to scan the finger.

A nice step forward

The first generation of this technology is found in particular on the Galaxy S10 and Note 10 from Samsung. If its efficiency is correct, it is not the fastest. Qualcomm is therefore back at the start of 2021 with a new, more efficient version announced at CES 2021.

The 3D Sonic Sensor Gen 2 is presented by the American manufacturer as 50% faster. The detection area was also enlarged to 8 x 8 mm instead of 4 x 9 mm, which corresponds to an increase of 77%, “the sensor provides a larger area for you to place your finger and allows the Qualcomm 3D sonic sensor to capture 1.7 times more biometric data “.

We should probably find this sensor on high-end smartphones in 2021. The Galaxy S21, whose presentation is scheduled for January 14, could very well benefit from it:
