Fingerprint scanners have been in the fashion of android marketplaces since 2018, but the technology has not improved for a while, as it is difficult to

Xiaomi has patented a new fingerprint scanning technology that allows the user to use the fingerprint sensor by touching any part of their screen. Now you don’t have to try anymore to turn on your phone or place your finger on the finger reader, because you can do this by touching anywhere on the phone’s screen. This is a very privacy issue.

It will have a set of infrared LED light transmitters under the capacitive touch screen layer and above the usual AMOLED display.

        Wow. I wouldn’t have come up with that myself, thx.
