Last year, Qualcomm introduced the world’s first ultrasonic fingerprint scanner, a 3D Sonic Sensor, which captured the texture of the skin, even through the dirty screen. Now the company showed the new version, Sonic 3D Max, able to simultaneously scan two prints.
Until recently, smartphones and other mobile devices find it difficult to scan the fingerprint as fast and accurately as did the special scanner on the rear of the unit. Apple generally refused for screen scanners for authentication in the face, reminded in Venture Beat.
Qualcomm has decided to move in the direction of the scanner, located under the screen, despite the fact that this technology was criticized for the danger it allegedly allows unauthorized access if the owner uses a protective film on the screen.

In response to criticism appeared sensor 3D Sonic Max with improved safety. Now, in order to start working with the phone, you need to simultaneously put two fingers to the screen. The surface scan was 17 times more than before – now it’s “the biggest fingerprint sensor”, the company said.
The accuracy of Sonic 3D Max also increased in 20 times, which also makes it much more difficult for scammers and reduces the risk of errors. In addition, the scanner began to work faster.
It is not clear when exactly we will see Sonic in 3D Max devices, but we can assume that this will happen in 2020.

The key question is what companies will use this technology. Last week the Korea Times reported, for example, that Samsung is going to completely abandon the technology of ultrasound scanning of prints, given its lack of security.
