Yeah. When I'm having a stroke!
Meanwhile I'm trying to get rid of a crapload of gnats which have invaded my home.
Running around setting the gnat traps will probably give me a heart attack, so I won't have to worry about the stroke.
It’s all pointless.
So you use your heartrate, your thumbprint, your brainwave, etc, whatever.
It sends a signal and when it matches the other signal you have access.
So all it takes is a captured signal.
Ie, a recording of someone’s heard that they used to get access previously.
In other words you don’t need to have a eye scan if you have a very realistic picture of the eye scan.
Just take your morning baby Aspirin, if you can get the cap of the bottle.
