Qualcomm's new in-display ultrasonic fingerprint reader allows two fingers to be read simultaneously



Qualcomm announced a version of its second-generation ultrasonic fingerprint sensor, the 3D Sonic Max, which promises to solve the problems with the original 3D Sonic sensor by offering a 17-times larger sensor. In fact, the 3D Sonic Max is so large that it can read two fingerprints simultaneously using Engadget for additional authentication.

The company's first-generation ultrasonic fingerprint reader, the 3D Sonic sensor, promised improved reliability and security over existing optical fingerprint readers on the display. Despite a high-profile debut in Samsung's Galaxy S10, the first-generation 3D sonic sensor has been plagued with issues including getting the smaller sensor to read prints accurately, slow speeds, and a blatant vulnerability from some types of screen protectors was caused was not resolved until October.

The new sensor should solve these problems, since it is considerably larger: Where the old sensor measures 4 x 9 mm, is the new 3D Sonic -Max 20 mm x 30 mm or 1

7 times larger. According to Qualcomm, this should help solve most of the previous problems. The larger sensor makes positioning a fingerprint much easier (to avoid positioning problems).

In an interview with CNET Alex Katouzian, SVP and General Manager of Mobile at Qualcomm, noted that the new 3D Sonic Max should avoid the problems with screen protection by making it clearer when reading Fingerprint recorded on the larger scanner size. The option of scanning two fingerprints simultaneously should also improve security options.

One thing that does not change is the speed. According to Katouzian, fingerprint scanning with the new sensor takes about as long as the old one.

We need to put the new 3D Sonic Max through its paces to see if the original 3D Sonic sensor's problems are actually solved. It is not yet clear which companies will actually use the 3D Sonic Max in devices. However, there should be more news in 2020. A potential customer could be particularly interesting: Early rumors suggest that Apple investigates the use of technology by Qualcomm Already next year, the iPhone will be equipped with a fingerprint reader for the display (after MacRumors ).
