RF tagging and identification

["Ward, David" <David.Ward@xxxxxxx>]

I remember reading about a product called "FindEntity" a few
years ago it
used Texas Instruments 13.35MHz RFID tags.  The system was designed to
track
important documents in offices.
Readers were attached to the nearest networked computer and
strategically
placed under desks and in filing cabinets.  The tags were simply stuck
to
any document that needed to be tracked (They were the thin foil aerial
type)

If a user wanted to know for example "Where's did this week's radio
times
go?" they would just query the system via a computer and it would
respond
with the location of the last 'reader' to have seen the tag attached to
the
document.

They even had a 360degree steerable laser pointer that could be attached
to
the ceiling and would spin around and point to the loctaion of the
document
- presuambly for use if you had tons of filing in one office.

I always dreamt of having one of those systems at home.  The trouble
is
EVERYTHING would need a tag :?)

P.S. 
Finding our two cats would be easier too,  and they're already
tagged  :-)
