Qualcomm unveils new ultrasonic fingerprint scanning tech

Fingerprint scanning and authentication technology seems set to take the next step with Qualcomm’s cleverly named Fingerprint Sensors.
The other clever bit is the use of ultrasonic technology to scan fingerprints, which allows the existence of a significantly thicker piece of material between the sensor and the finger – twice as thick in the case of glass (800 µm). It also has features such as detection of directional gestures, underwater fingerprint match and can also use hear
