Qualcomm aims for an increase in security with this second-gen 3D Sonic Max

The first generation 3D Sonic Sensor assured improvement in terms of reliability and security when it was launched in Samsung’s Galaxy S10. But later on, it had lots of issues such as getting the smaller sensor to read prints accurately, slow speeds, and a glaring security hole caused by some types of screen protectors that were only fixed in October.

This time, the second-generation fingerprint sensor is claimed to be 17 times larger, which solves the problems of original 3D Sonic. The old sensor measured 4mm x 9mm whereas the new 3D Sonic Max is 20mm x 30mm. To prevent positioning issues, the bigger sensor will make it more convenient to place a fingerprint.

According to an interview, Alex Katouzian, SVP, and general manager of mobile at Qualcomm explained that with the latest 3D Sonic Max, the screen protector problems should be avoided. This is said to enable capturing a clearer complete fingerprint when reading, because of the larger scanner size.

Aside from that, there is an option to require two synchronized fingerprints to be scanned together in order to heighten security. Katouzian added that scanning a fingerprint will take almost the same amount of time as the older one did.

There’s still no information yet to which companies will utilize the new 3D Sonic Max, but there might be updates next year. Also, rumors said that Apple is discovering using Qualcomm’s tech to add an in-display fingerprint reader to the iPhone as early as 2020.
