[hackerspaces] RFC: security alarm and access control systems in use

[Bob Bownes]

Pretty simple implementation. Card reader, microcontroller, wifi or
ethernet, and some Big Ass Relays. The list of authorized cards is sent out
to the stations when it is updated. The card must be present in the reader,
and, if valid for that station, turns on the relays placed in the power
line. Pull out the card, relays turn off. Sure, you can hack it by taking
the box apart and bypassing the relays, but by the time you get done doing
that, someone else will have come in and asked wtf is going on. Not to
mention the cameras.
