I worked for a company once and they had a eye scanner to open the door to the server room, and it had a voice, all you could hear when some was trying to get in was " move back a bit, move left a bit, move right a bit"

It didn't last long.

I can imagine trying to access early morning and the scanner being uninterested in bleary-eyed humans 😆

I know, it was a bank, insane amount of security.

Any reverification noise and I think the project will be flat on its arse!

I read way to much sci-fi

Lured in with the Eyeball on a stick? :D
