Qualcomm today announced 3D Sonic Max, a new ultrasonic sensor for in-display fingerprint readers. It offers a sensing area 17 times larger than the previous sensor offered by the company, eliminating the need to carefully align your finger with the sensor area. The larger sensing area also enables two-finger authentication for greater security. Qualcomm also promises greater “accuracy” compared to previous sensors.
