CrucialTek unveils the tiniest fingerprint sensor, ready to go in your future phone

Moving fingerprint sensors on the side was the greatest idea about them this season, as when they are embedded in the home key, you have to, well, have a home key, with the space it takes on the bottom bezel. When you put them on the back, you can't unlock your phone if it is lying flat on the desk without first having to pick it up, and so on.

The side positioning in the power/lock key, like on the new Sony Xperia Z5 trio, is a great compromise, but there is something even better coming down the pipe, again from CrucialTek. We already told you that the biometric juggernaut scored a patent approval of its embedded fingerprint sensing technology, which can be installed in an area on the display panel itself, and that will probably appear in handsets at some point, but now the CrucialTek team has a simpler solution.

The company unveiled new fingerprint sensing Muon algorithms that allows a minimum recognition surface area of just, wait for it... 8 mm2. Of course, with all packaging paraphernalia, the sensors will end up at about 18.72 mm2 (5.2 x 3.6 mm) surface area, but just compare that to the current units that are on the back of the Nexus 5X or 6P, which are 64 mm2 (8.0 x 8.0 mm) in size.

These compact finger scanners can now be slapped anywhere - on thinner, more elegant buttons, and smaller home keys that will eventually allow for better screen-to-body ratios of phones with fingerprint sensors. Not only that, but CrucialTek increased the recognition speed and security of its new sensors with the Muon algorithm, making their invention a very compelling package, and has supplied it to phone makers for review, so we might see it in handsets as soon as next year.

I expect for FP sensors to start moving to the side (if not into screen), but I have one problem with it (same problem I have with phones that have it on the back) - when the phone is laying on table and you need to access something - you're forced to pick it up, pushing against the side to activate the sensor would just push the device unless you grip it from both sides, and if they make the sensor to always reading (so you wouldnt need to activate by pressing on button first) - that would allow accidental unlocking, but worse - it will put a strain on battery I think. Just my 2 cents...

I don't see why you'd need to pick it up if the sensor is on the side I can easily turn my phone's screen on without picking it pick from the table, I'd imagine it was be the same if there was a fingerprint reader there Most sensors don't need to be pushed to be activated, some of them even work with just a brief tap I hope most Android phones next year will use Qualcomm's fingerprint reader under the screen And Apple have something similar and ditch the home button for 3D Touch gestures

I'm sure by the time they implement it - it will work as you described... still would feel awkward, but how do you prevent accidental unlocking if it doesn't require a push first (let say putting into the pocket. I think they should concentrate on in-screen implementation... But regarding 3D Touch (still hate that name!) I bet that that's where Apple is heading. I always liked a physical home button, as it illuminates doubt and builds muscle memory (I hope you know what I mean) - forcetouch with proper haptic feedback (like it feels when using 3d touch) is a way to build that muscle memory and diminish unwanted input. anyways, Yey for innovation!

Good point about accidental unlocking. Fingerprint readers are getting too fast now! Agreed,in-screen is the future, hopefully near future. And yea feedback is also very important for force touch

How about the screen itself becomes a sensor. No home button. Press anywhere on the screen to unlock at any angle.

It can be quite erroneous... I Rather have a designated area... If you used a 6s FP, you'll know how EFFING fast that sensor is... I dont use my thumb for Apple Pay anymore - it unlocks the phone during the double-tap nearly every time - you gotta be superfast if you want to use your FP unlocking finger to activate Apple Pay.

Pressure sensitive FP sensor in displays itself is the future :)

Hauwei, LG, Google(Nexus 5X/6P), ZTE, Oppo, Sony, HTC, Coolpad, Meizu, Gionee, OnePlus, LeTV, QiKU, ZUK, Alibaba YunOS based smartphones, BLU, Gigaset(Siemense) Nextbit and MS(Black keyborad for Surface Por 3/4), Fujistu, etc. Most smartphone manufacturers selected FPC sensors, Precise algorithms and CrucialTec scanner modules except Samsung and Lenovo. Xaiomi, TCL-Alcatel, Nokia, Motorola and India's three Local manufactures only didn't determine. But, I guess...it's coming.

Fingerprint readers are now essential and standard functionality
