Qualcomm's 3D Sonic Max in-display fingerprint scanner is 17x bigger

04 December 2019 0

Qualcomm has unveiled 3D Sonic Max as its second-generation ultrasonic in-display fingerprint scanner. It is a direct successor to the original 3D Sonic Sensor that made its debut with the Samsung Galaxy S10. It did not turn out to be a successful debut as users complained about various issues. The new version hopes to rectify those issues and offer improved performance and security.

The biggest difference between the new 3D Sonic Max and predecessor is the physical appearance. The newer offering is said to be a whopping 17 times larger with 20mm x 30mm measurements. Qualcomm says that it is so big in size that it can be used for recognizing two fingers at once. The big size is said to be beneficial in offering more speed and better positioning space for using one's finger to unlock the smartphone.

In the official announcement post, Qualcomm said:

"Katouzian also announced 3D Sonic Max, the latest version of our ultrasonic fingerprint sensor. 3D Sonic Max offers a recognition area that is 17x larger than the previous generation, allowing for increased security via simultaneous two-finger authentication, increased speed and ease of use."

Qualcomm has not shared details about when we will be seeing the new 3D Sonic Max fingerprint scanner making an appearance in smartphones. We can expect it to become available through flagship launches but considering many OEMs are now focusing on facial recognition tech, it will be interesting to see exactly how many phones will be released with this new tech.
