The majority of fingerprint scanners can be found either on the back of a smartphone or on the front, embedded in the home button. But it looks like that status quo is soon about to change. According to a report from The Investor, CrucialTec, a manufacturer of fingerprint modules based in South Korea, will launch its on-screen fingerprint scanning solution that allows you to unlock your device by placing a finger on the screen sometime this year.

This means that we can expect to see the first smartphones featuring the new fingerprint technology hit the market in 2017. Unfortunately, CrucialTec did not reveal an exact time frame or the smartphone manufacturers it is currently working with.

The new technology is called Display Fingerprint Solution (DFS) and has apparently been getting positive reviews from clients that are testing it out, especially from those that are based in China. The module can be embedded under the smartphone screen and is capable of detecting touches as light as a single hair. It can extract high-resolution fingerprints at 500 dots per inch.

DFS is also a lot safer than current fingerprint scanners that are available, as it can recognize multiple fingerprints at once. But this is just the beginning. CrucialTec said that it is also working on an upgraded solution that will hit the market next year. What makes next year’s version better is that you’ll be able to place your finger on any part of the screen to unlock the device, and not just on a specific area.

Fingerprint sensors that sit under the display just might be the next big thing and would make smartphones a lot cleaner and nicer to look at. The technology is also coming at the right time: we expect to see a lot of devices with small bezels around the screen in the near future, like the soon to be announced LG G6 and Samsung Galaxy S8.

Small bezels below the screen mean that smartphone makers have to place the fingerprint scanner on the back, as there’s just not enough room below the screen anymore. But not everyone is a fan of rear-mounted scanners. This new technology will change that, so smartphone makers will still be able to choose where to place their fingerprint module.

    What if the fingerprint sensor on the back of the S8 is just a backup for a fingerprint sensor in the screen?

    • mreveryphone

      Mind blown…

    • Dwayne Edwards

      Man, im still holding onto the hope that its the heart rate sensor on the back and that the actual fingerprint sensor is under the screen

    • Marius Tomas

      I was kind of thinking the same…… trying to be optimistic

    • philnolan3d

      Why have 2?

      • Andrew Collins

        One on the front so you can use it when you pick it up and one on the back if the phone is screen down

  • mreveryphone

    Making the whole screen a fingerprint scanner would be sick!

    “you’ll be able to place your finger on any part of the screen to unlock the device … Fingerprint sensors that sit under the display just might be the next big thing and would make smartphones a lot cleaner and nicer to look at.”

    Yup. Nothing like a bunch of greasy fingerprints all over your display to make your phone look clean.

    Yes, I get the point, but you were asking for it with the stupid way you worded that.

      I’m ready to use the Iris scanner anyway!

        lasers in your eyes. Always a good thing

            Infrared LED/laser – could hurt your eyes in the long run. There’s no extensive safety research that’s been done.

      • philnolan3d

        The iris scanner doesn’t work in all situations especially if you’re not picking up the phone.

    • Lucas

      Your fingers touch the screen regardless if the scanner is there or not.

      • Daggett Beaver |dBz|

        Like I said, I get the point, but it just struck me as funny. Put your fingers all over the display and it will be clean!

    • Jason Harris

      I mean you touch the display anyway when you are using the device so it makes absolutely no difference

    • philnolan3d

      So you never touch your phone screen?

  • Jason Stephen

    Isn’t this the same thing as the Synaptics under the screen fingerprint sensor which was rumoured to be introduced with the S8?

    • Snagaghash

      I believe so.. I wanted it to be embedded so bad with the s8.

  • Kody

    Didn’t Snapdragon already have something like this?

  • philnolan3d

    I hope we can see this in the Note 8.

  • Paul Colella

    Qualcomm has had Sense ID for a while now — well over a year since I read the first article about it. Why is that not being adopted? It’s a much more thorough scanning technology and can sense through all kinds of material.

  • Choda Boy

    Isn’t the iPhone 8 rumored to have this?
