My IBM desktop has RFID. It connects to the board and runs
out to the front. The cable ends with a little semi flat rubber shielded wand.
The manual for this mobo has it listed, but offers no
useful details.
I've read basics about RFID and vaguely why IBM started to
incorporate these devices in some desktops. Missing the whole
of IBM's idea and uncertain of what this specific piece of hardware
does, here's some questions.

The wand is Foxconn RFID, but what is it exactly?
Does Linux offer anything advanced for this hardware?
Let's say I wanted monitoring with RFID, could I do that in Linux?
thanks
