Unless disabled by timeout, restart, or otherwise manually I'm curious to know why that would be?

Of course the dude had to know this was a one way trip, I'd have wiped everything but then again maybe they didn't care at that point.

It is hit or miss. The fingerprint button is also looking for the electrical signals of a living person. Apparently, that doesn't end immediately upon death.

Source? Sounds like scifi movie stuff to me, but I'd be interested to read/see more about it

Your body doesn't all die at once. The parts that need a constant flow of oxygen die within minutes, while some parts take hours. Tissues like skin, tendons and heart valves are viable for harvest for as long as 48 hours after death.

I don't know how long a fingerprint would work after death though. I imagine it depends on the type of scanner. An optical scanner would probably not care. I'm not sure about ultrasonic. Thermal and capacitive would probably stop working within minutes of death.

Lol not that. I'm well aware of that. I meant a source for "fingerprint readers are looking for an electrical signal too" as I'm very sure I've heard about them being defeated with a high enough quality reproduction of the finger (read: not flesh at all, let alone alive)

Oh, I did a dumb. Capacitive readers use the body's natural electrical signal to form an image of your fingerprint. You can trick them by using something conductive and running the right amount of electricity through.

Dead people don't work though. Not for very long at least.

Capacitive sensors don't measure the body's signals. Capacitance is a physical property of a material. The sensor puts out a signal and measures the response.

I can use a gallon of milk to scroll my phone. Just tried.

Hit him with a TENS machine then

Wiping isn't a 100% thing with either Hard disks or Flash. He should have thrown everything into a wood chipper. And yes, this absolutely has to be a one way trip. Either they get you, or you turn the gun on yourself. Nothing good will come of you surviving.
