RFID tags -- what frequency?
 

I got an old IBM desktop computer to use in the shack, and when I opened
it up I found it has an RFID feature.

Of course I will disconnect the thing, but, just out of curiosity, what
frequency do these things work on? (I understand that RFID tags can be
either active or passive, but this one presumably is active, since it
has an antenna that plugs into the mobo. I have read that they all use
the same frequency, but each individual item has a unique code.)

Forget the RFID things in old IBM machines, you should worry about the
little stick-on "rip-off" gadgets that everyone uses (Best Buy,
Wal-Mart, CompUSA). These all-white or all-black rectangular gadgets in
particular are passive, but they are pervasive. You need to take them
off and stick them on the back of your friend's pants/shoes/hat so that
it sets off everything on the way out of the store. Plus, if you can do
it to a stranger, or even better, a nun, and if enough of us do it, they
will ditch these infernal things. That will get the Pope involved.

Thus fulfilling the Biblical pronouncement of Revelation, the whole
"666" thing, and so on.

If those things operate on 666 MHz, I'm a believer.
