It’s a pretty sad state; don’t you think?

Only the thumbs have a pulse.
govt employees are evil
No, we aren’t and apparently some people endorse this.
Until it’s them.
The touch screen itself is looking for electrical charges - that’s how it perceives the world. The screen can neither see optically, nor feel the touch - it looks for patterns in the charges.
If that is true, no wonder it doesn't work right. I know the basics of capacitance touch screens, and I would have never thought there would be any way to distinguish to any degree of accuracy between one person's finger and another.
Visually yes. But with variations in the capacitance charge of people's fingers? I don't see it.
You can always use the phone though, with the pass thingie?

A capacitance fingerprint reader leverages a handy property of your skin: The outer layer of your skin (your dermis), where your fingerprint is, is non-conductive, while the subdermal layer behind it is conductive. When you touch the iPhones fingerprint sensor, it measures the minuscule differences in conductivity caused by the raised parts of your fingerprint, and it uses those measurements to form an image..
The article says that the capacitance reader has a resolution of about 500 dpi - though it uses the home button, not the screen.
500 dpi? That would be enough to get an image of a finger print, but it is astonishing that they can measure the differential between peaks and valleys of the skin on your fingers. I guess they have made some progress since I last looked at this technology.
As I understand it; you can be compelled to give up biometrics, but not your password.
Why would I try to flee the cops?
Red herring argument.
Try again.
