Samsung's Newest Phones Read Your Fingerprints With Ultrasonic Sound Waves
An anonymous reader quotes CNET:The Galaxy S10's in-screen fingerprint scanner may look just like the one on the OnePlus 6T, but don't be fooled. Samsung's flagship Galaxy S10 and S10 Plus are the first phones to use Qualcomm's ultrasonic in-screen fingerprint technology, which uses sound waves to read your print. Related to ultrasound in a doctor's office, this "3D Sonic Sensor" technology works by bouncing sound waves off your skin. It'll capture your details through water, lotion and grease, at night or in bright daylight. Qualcomm also claims it's faster and much more secure than the optical fingerprint sensor you've seen in other phones before this. That's because the ultrasonic reader takes a 3D capture of all the ridges and valleys that make up your skin, compared to a 2D image -- basically a photo -- that an optical reader captures using light, not sound waves.Read more of this story at Slashdot.
