The company said the sensors bring new features to the previous Snapdragon Sense ID fingerprint technology. The prototype has Qualcomm's new sensor fitted beneath the display, according to Engadget.

Qualcomm Fingerprint Sensors are designed as both an integrated solution with Qualcomm® Snapdragon™Mobile Platforms, and as standalone sensors that can be used with other non-Snapdragon Platforms. Qualcomm's new glass and metal fingerprint sensor technology is slated to be available to OEMs later this month, while the display technology won't ship to OEMs until the fourth quarter of 2017.

The sensors will be available in multiple forms of hardware, including display, glass, and metal varieties. It doesn't appear to be a speedy as traditional smartphone fingerprint sensors, but that's not surprising since the technology is still in its infancy and hasn't yet been incorporated into any consumer devices.

These new fingerprint sensors have been designed for use with the Snapdragon platform, but there are stand-alone sensors that'll work in other situations too. With Qualcomm's new Fingerprint Sensors, OEMs can integrate fingerprint readers that'll work through displays, glass, and metal, helping them to make new and interesting smartphone designs.

Qualcomm, the leading chipset maker in the industry has just announced the new ultrasonic fingerprints for smartphones and tablets at MWC Shanghai.

"We are excited to announce Qualcomm Fingerprint Sensors because they can be created to support sleeker, cutting-edge form factors, unique mobile authentication experiences, and enhanced security authentication", said Seshu Madhavapeddy, VP of Product Management, for Qualcomm.

Vivo said that this was a financial rather than technical constraint: it would be possible to apply fingerprint sensors across the entire screen, but this would be significantly more expensive.

Apple obviously isn't the only one working towards this goal, as Vivo also plans to release a phone with an under-display fingerprint scanner, which we're about to learn quite a lot more about. A device will need to be using a display panel under 1200 μm, meaning traditional LCDs won't work.

Commercial devices with Fingerprint Scanners for Display are expected to launch in Summer 2018.

Qualcomm's new Fingerprint Sensor can work under glass, display and metal.
