Vkansee’s under-glass fingerprint sensors to debut in laptops before smartphones

The next step for fingerprint sensors on smartphones is for them to sit under the glass, and that’s rumored to be a feature on Apple’s next iPhone. Vkansee, a startup in New York, has already patented an under-glass optical fingerprint sensor — but the company is utilizing it first with Windows laptops.

At Mobile World Congress, the startup is demoing its prototype optical fingerprint reader on a Lenovo laptop utilizing Windows Hello, Microsoft’s face, fingerprint, or iris recognizing software that enables secure sign-in into your computer.

There are varying types of fingerprint sensors, but the most common ones found on smartphones today are capacitive scanners, which use electrical currents to collect data about a fingerprint. Vkansee president Jason Chaikin told Digital Trends that capacitive scanners are “great,” as they are cheap, fit into phones well, and consume very little power.

So why do manufacturers want to ditch them? Smartphone design. Manufacturers always need to cut a hole because it’s incredibly difficult to have a capacitive sensor under glass — they would need to etch the glass to attempt to put the sensor underneath.

Optical scanners have been around for a long time, but until now they have been big and bulky — they’re the sort of scanners used at border crossings and for background checks.

“A small light flashes through glass and it goes through a lens,” Chaikin said. “An optical sensor is a fixed, focal-length camera that captures a picture of your fingerprint.”

Vkansee’s optical sensor can read through 2mm of glass, making it optimal to be embedded under a smartphone’s glass display. Synaptics also announced an optical fingerprint-sensor for smartphones last year.

Vkansee’s testing its prototype on a Lenovo laptop, and the company claims its “high-resolution sensors are ultra-thin, anti-spoof, water- and sweat-resistant, and read fingerprints at a resolution up to 2,000 pixels per inch.”

The company said its evaluation kits are in testing with various manufacturers, and last year it announced a software licensing partnership with Precise Biometrics, a fingerprint software company that offers fingerprint matching algorithms to the likes of Huawei, Google, Xiaomi, Lenovo, LG, and more.

Chaikin said Vkansee’s technology will debut in laptops this year, and likely on mobile devices at a later time.

The Qualcomm 3D Sonic Max fingerprint sensor lets you scan two fingers at once
ZTE Axon 10 Pro fingerprint sensor

Just a few days after rumors emerged that Samsung might be moving away from Qualcomm's ultrasonic fingerprint sensor, Qualcomm has announced a second-generation of the tech. The new sensor is called the Qualcomm 3D Sonic Max, and it offers a number of upgrades over the previous-generation sensor. The company announced the tech at its annual Snapdragon Summit, which I was flown out to.

Details about the new ultrasonic fingerprint sensor are still a little scarce, but what we do know is that it will offer a recognition area that's 17 times larger than the previous-ten sensor. The result? According to Qualcomm, the new sensor allows for increased security. In fact, the extra area essentially means that you can use two-finger authentication, instead of having to stick with one.

New 9800X3D leak: ‘Strong generational boost in games’ is just 8%
AMD Ryzen 7 7800X3D held between fingertips.

AMD's best processor for gaming is right around the corner. Through various leaked benchmarks, we've already learned that it might disappoint, and today's leak only serves to confirm that. According to leaked AMD data, the Ryzen 7 9800X3D may offer a subtle improvement in gaming -- although it'll still be better than what most of the Zen 5 lineup has been able to provide.

VideoCardz was able to obtain what appears to be an official marketing description of the Ryzen 7 9800X3D. The blurb reveals things like the predicted improvement in instructions per cycle (IPC), gaming, and multi-threaded workloads. It looks like the real deal, but as with any other leak, it's important to remember that we'll only learn the full story once we test the CPU ourselves.
