Samsung’s Ultrasonic Fingerprint Scanner Does What Apple Couldn’t Do

Prior to the launch of the Samsung Galaxy S10 series, there have been smartphones with in-display fingerprint scanners. However, this is the first time a smartphone features an in-display ultrasonic fingerprint scanner. This is because the ones before it are optical and not ultrasonic. Basically, it uses light to create a 2D image of your fingerprint. On the other ultrasonic type, sound waves is used to make a 3D structure of your finger offering more accuracy.

The ultrasonic scanner used in Samsung’s flagships is actually from Qualcomm, which is part of the added perks of the Qualcomm Snapdragon 855 on board. In fact, this is the third generation of the ultrasonic scanner by Qualcomm. A vision since 2013 when the company acquired Ultra-Scan, a company that produced ultrasonic readers for the US government.

How to Guarantee Your Phone’s Fingerprint Reader Works Every Time

The fingerprint reader on your iPhone or Android phone always seems to fail enough on the first try. It can be anything from your fingertip not fully covering the sensor, wet hands or possibly the phone didn’t get an accurate read when you first registered your fingerprint.
By registering the same fingerprint more than once, you’re increasing the chances of your phone capturing enough data to unlock the first time. That’s because when you register your fingertip in the phone settings, it isn’t always clear which parts of your print the software has captured. A somewhat helpful animation or audible feedback will urge you to lift your finger to capture more area, but that doesn’t necessarily reflect the data your phone’s actually storing. read more
