Re: Nope missing an obligatory element
Funny you should mention a fridge magnet as an authentication device.
I used To work for an ISP and the pencil botherers decided that every internal door should have magswipe security which doubled as timecards and basic workplace snooping. My domain in the server room and "control suite" already had good old fashioned pin number locks.
Cue much frustration and general gnashing of teeth as people forgot their ID cards at home or on their desks.
Until some scruffy intern in the web design department discovered that using any magnet from any of the memo boards liberally distributed around the company would open any door with a quick swipe down the card slot.
Bloody expensive but about as secure as a politicians moral compass.
