This supersonic fingerprint scanner maps your sweat poresHigh-frequency sound waves help this new scanning technology cut through grime, and make authenticating your identity with your finger more secure than ever.
Qualcomm has cooked up a new way to get more accurate fingerprint scanning even if your finger is covered in goop or wet. I'm Jessica Dolcourt and I'm gonna show you how this works. Now this is called the Snapdragon sense. ID, 3D, fingerprint technology. It's quite a mouthful. But what it basically means is that the company is using ultrasonics, so that's high frequency sound waves, to get your fingerprints. That means also that you can embed this. Directly into the bottom of the device, instead of having to embed it into a button. So for a very quick demo, I'm going to press the area on the bottom of the screen, and my fingerprint, or part of my fingerprint, will show up here on the right. The sound waves can actually collect quite a lot of data about your fingerprint, and what makes it unique. Including the ridges on the edge of your finger, and your sweat pores. The idea's that you'll be able to replace most of your passwords with just your fingerprint scan and that it will be much more secure. We'll start seeing this new kind of 3D fingerprint scanning in devices starting in 2015. I'm Jessica Dolcourt for CNet, you can read much more about this at cnet.com.
