“The 3D Sonic Max is claimed to be more secure and faster”

With more and more smartphones achieving the holy grail of all-screen fascia, under-display fingerprint sensors are becoming commonplace. While most phonemakers are opting for optical fingerprint scanners, Qualcomm offers ultrasonic fingerprint reader technology that’s more secure. Samsung’s Galaxy S10 and Note 10 flagship utilise the same, and in a bid to attract more OEMs towards its solution, the San Diego-based company has announced its upgrade today. Christened 3D Sonic Max, the sensor covers a larger area that enables several interesting capabilities. 

The biggest benefit of a larger area, which is 17x bigger from the previous iteration, is the fact that it can authenticate two fingers simultaneously. Yes, that means that you could choose to register two digits for unlocking the phone among other things. To recall, Vivo’s Apex also offered a larger area for similar purposes, and we can expect Qualcomm to offer support for various gestures. Since the sensor is larger, it’ll also be able to capture a more accurate and clear image of your finger, which in turn, should produce a highly-secure authentication system. Qualcomm is also highlighting that the new sensor is faster.

Both the speed and accuracy are important aspects since the under-screen fingerprint readers still haven’t been able to match the conventional fingerprint modules. During the launch, Alex Katouzian, senior vice president and general manager, mobile, Qualcomm Technologies, Inc also stated that the 3D Sonic Max will not be just available for phones. It can also be used in automotive, IoT devices and more. Sadly, Qualcomm hasn’t divulged any other information about the 3D Sonic Max technology, so it remains to be seen if it’s adopted widely by smartphone manufacturers.
