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.

The Galaxy S10’s fingerprint sensor can be fooled by a screen protector
galaxy s10 plus fingerprint

The advanced ultrasonic fingerprint scanner on the Galaxy S10 and S10 Plus can be fooled by a simple film screen protector — and the company says it will push out a software update to fix the issue as quickly as possible.

The problem was first raised in a report from British newspaper The Sun. According to that report, adding a simple film screen protector from eBay allowed any fingerprint to unlock one woman's phone -- including her own unregistered left thumbprint, her partner's fingerprints, and even a relative's prints.

The XPS 16 is fighting an uphill battle against the MacBook Pro

It took a few years, but Dell finally updated the design of its two largest XPS laptops. The XPS 15 gave way to the XPS 14, while the XPS 17 was replaced by the XPS 16. The latter gained the ultramodern look of the XPS 13 Plus, complete with a glass palm rest, a hidden haptic touchpad, and a row of LED function keys.

It's a significant update but places the XPS 16 in direct competition with the Apple MacBook Pro 16. That's an excellent matchup with proven performance and battery life and an elegant design that's solid, if a lot more conservative.
