Qualcomm’s new in-display ultrasonic fingerprint reader can learn two fingers without delay

Qualcomm has introduced a second-generation model of its ultrasonic in-display fingerprint sensor, the 3D Sonic Max, that guarantees to repair the problems with the unique 3D Sonic Sensor by providing a sensor that’s 17 occasions larger. The 3D Sonic Max is so huge, in actual fact, that it may learn two fingerprints without delay for additional authentication, by way of Engadget.

The corporate’s first-generation ultrasonic fingerprint reader, the 3D Sonic Sensor, promised improved reliability and safety over present optical in-display fingerprint readers. Regardless of a high-profile debut in Samsung’s Galaxy S10, the first-generation 3D Sonic Sensor was tormented by points, together with issues getting the smaller sensor to learn prints precisely, gradual speeds, and a obvious safety gap brought on by some forms of display protectors that was solely fastened in October.

The brand new sensor appears to handle these points, because of being vastly bigger: the place the previous sensor measured 4mm x 9mm, the brand new 3D Sonic Max is 20mm x 30mm, or 17 occasions bigger. In accordance with Qualcomm, that ought to assist resolve a lot of the earlier issues. The larger sensor makes it far simpler to place a fingerprint (to keep away from the positioning points).

And in an interview with CNET, Alex Katouzian, SVP and common supervisor of cell at Qualcomm, famous that the brand new 3D Sonic Max ought to keep away from the display protector issues by capturing a clearer full fingerprint when studying because of the bigger scanner dimension. The choice to require two simultaneous fingerprints to scan collectively additionally ought to assist enhance safety choices.

One factor that gained’t change, although, is the pace. In accordance with Katouzian, scanning a fingerprint will take roughly the identical period of time with the brand new sensor because it did with the previous one.

We’ll must put the brand new 3D Sonic Max by its paces to see whether or not it truly solves the issues of the unique 3D Sonic Sensor. There’s nonetheless no phrase but as to which firms will truly be utilizing the 3D Sonic Max in units, though there needs to be extra information on that someday in 2020. One potential buyer might be significantly fascinating: early rumors declare that Apple is exploring utilizing Qualcomm’s tech so as to add an in-display fingerprint reader to the iPhone as early as subsequent 12 months, per MacRumors.
