Apple and Samsung has been struggling to create fingerprint sensors that can work behind touchscreens, but Qualcomm has apparently beat them to the punch: the company revealed their “Qualcomm Fingerprint Sensors” technology during MWC Shanghai, which uses sensors that can scan through 800 micrometers of cover glass, work underwater, and even pick up a person’s heartbeat and blood flow as an extra measure of security. Vivo managed to get first dibs on the technology.



Your fingerprint scanners are going down next summer. As in they’re going below the glass and behind the back of your phone, according to Qualcomm. At Mobile World Congress Shanghai on Tuesday, the chipmaker announced new fingerprint sensors that can work underneath your phone’s display, through metal and glass, and underwater. Qualcomm expects the first commercial devices using fingerprint sensors underneath glass and metal to start selling in early 2018, while sensors that go under the display should show up by the summer of 2018.
