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.

Why is this a privacy issue?

The phone always knows who is using it, not just when you want it to know.

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

Is this currently being abused by any OS or apps?

I didn’t know android introduces a permission for the fingerprint, I’m still on android 10. Good to know that you can disable that in the recent versions

That’s pretty dope, but I have a Xiaomi phone and the current fingerprint reader is really fast and good enough anyway tho.

Just wait until all of those McDonalds touchscreen kiosks have these allowing them to know who purchased what where and at what time. Now imagine every interaction with any shopping experience moving to touchscreens like this. Coming soon to every store near you.
