In the framework of the Qualcomm Summit 2019 that took place in Maui (Hawaii), the company introduced a new generation ultrasonic fingerprint sensor called 3D Sonic Max with the promise of better quality of use. .

Also during this event, we were able to get a hands-on 3D Sonic Max demo and realized that this is not just a matter of increasing the size of the sensor. Previously the size of the ultrasonic sensor was only about 4mm x 9mm, making it difficult for users to place their fingers correctly to be able to scan.
With 3D Sonic Max, this area is increased by 17 times, which is 20mm x 30mm and in the picture below you will see it takes up a large area of the screen of the phone. A representative from Qualcomm at the experience counter said that with the new generation sensor, we do not need to look at the phone but we can easily unlock it with our fingers.
Here, we find that the actual fingerprint recognition speed does not seem to improve compared to the previous one, but certainly with this new version we will manipulate the position of the finger faster so it will solve it somewhat solve the time issue as a whole.
In addition, users can increase the security of the machine by scanning both fingers, but of course the unlocking time will be longer than the normal way. Bad guys who want to fake fingerprints will also have more difficulty with this new type of sensor.

Vice Chairman Alex Katouzian at a meeting with CNET correspondents said 3D Sonic Max can overcome the flaw of ultrasonic fingerprint sensor encountered in recent years.
In addition to security and increased sensor size, Qualcomm also integrates the ability to read heart rate by placing your finger in the sensor area. A Qualcomm representative told us that this is a beta version and will not come with 3D Sonic Max by default. “If any OEM wants to integrate this feature, we will provide more,” the person said.
