In-display fingerprint scanners, first introduced with the Vivo Nex, have now come to be an industry standard and is found on most phones. Today, Qualcomm has announced the 3D Sonic Max fingerprint sensor that is taking its last-gen 3D Sonic tech to the next level.
As far as the in-display fingerprint scanner is concerned, the industry currently uses two main technologies. The first one relies on an optical image of your fingerprint while Qualcomm’s 3D sonic system makes use of ultrasound to get an impression of the prints of your finger. The newly-unveiled 3D Sonic Max sensor makes use of the same technology but is 17 times larger than its predecessor and makes fingerprint authentication much more secure.
According to Gordon Thomas (Sr. Director, Product Management), current in-display fingerprint scanners scan only a part of one’s fingerprint. The bigger surface area of the Sonic Max, a total of 600mm², does not only capture a complete fingerprint, but it also enables dual-fingerprint authentication. Qualcomm says that it’s aiming for a 1 in a million accuracy rate, which is the same accuracy that Apple claims for its Face ID tech.
