Qualcomm introduces faster in-screen fingerprint sensor

Capitalizing on the CES 2021 media wave, Qualcomm introduced its new fingerprint sensor, 3D Sonic Sensor Gen 2 .

The new sensor is 50 percent faster and 77 percent larger than the first-generation 3D Sonic Sensor. This means that when you put your finger on one of the cell phones that incorporate the second generation sensor, the unlocking will be faster and more accurate.

That the 3D Sonic Sensor Gen 2 is bigger is not a triviality. If you have a cell phone whose fingerprint sensor is integrated into the screen, you have probably seen yourself more than once putting your finger more than once without being able to unlock it. Well, Qualcomm ensures that its second generation sensor will leave these problems in the past thanks to a larger reading area: 64 square millimeters (8 × 8) compared to 36 (4 × 9) of the last generation.

The sensor's size also allows it to collect 1.7 more fingerprint details and read them 50 percent faster than the previous generation. The enhancement will likely also decrease the time required to configure this blocking option. In short, it will deliver a better quality experience.

Qualcomm said that the next-generation fingerprint sensor will be available on mobile devices earlier this year.

The first generation of the 3D Sonic Sensor was incorporated into high-end cell phones such as the Samsung Galaxy S10, Note 10, S20 and Note 20, so it is possible that the first cell phone to incorporate the second generation is the Galaxy S21 that will be presented this January 14.
