This is due to the fact that the 3D Sonic Sensor utilizes the ultrasonic method in order to scan fingerprints. Qualcomm claimed that this method is much capable than the optical-based solution that most in-display fingerprint scanners are based on right now since it able to capture full 3D images of one’s finger including its ridges and pores instead of just a 2D image. At the same time, Qualcomm also pointed out that the 3D Sonic Sensor still able to scan one’s finger even if it is wet or oily which made it more reliable than optical-based solutions. The company’s Senior VP and GM for Mobile, Alex Katouzian boldly claimed on stage that the 3D Sonic Sensor is the future of fingerprint technology which showed the level of confidence that the company has on its new product. For now, it is not known if any companies have adopted Qualcomm’s new sensor for their products. Nevertheless, Qualcomm has stated that the 3D Sonic Sensor will appear on new devices within the first half of 2019.
