mifare chips any one?
mifare chips from philips have successfully been incorporated into
watches.
if you are not into encoding data into the card, you can still use its
serial
number whic is guaranteed to be unique.
proximity cards are designed to work within a few inches from a
reader.
partly due to
it being powered by rf energy from the reader. (works like a radio's
antennae) and partly by design
..imagine walking down the hallway and triggering doors to open
as you
walk pass...

Room Occupation Detection
Mark,
My security pass for the office is like
this.
It only works within
half-an-inch or so of the detector, but I'm sure
that's partly by intent. I
guess it would be possible to use the same
principle and have detector in
ceilings or floors etc. As you suggest,
you'd need to shrink the chip, but
it's got promise. Maybe the sensors
could be hidden in the door surrounds
(like the anti-theft alarms in
shops)
to keep things tidy and the HA
controller keeps track of the movement in
& out. Do you know anyone with
retail outlet contacts ??
;-)
Cheers,
Tim H.

Tim,
What a funky idea...
Not
necessarily
one of these chips, but some form of proximity chip that
could go into a
watch / necklace / etc.

Indeed :-)
Bringing the thread
back
on track a little, presumably one of these devices
could be embedded
into a
watch / broch / necklace / ring / other commonly
worn item ?
Hey,
I've just thought, there's a great way to earn some brownie points
and
get
SWMBO-compliance for occupancy detection: Obtain one of these
little
chips,
have it embedded into a piece of expensive-looking jewellery and give
to
SWMBO as a gift for putting up with all of the HA toys. Bingo ?

Or,
"don't
worry dear, being a cyborg isn't really _that_ bad!", yeah
right
followed
by the delicate sound of her hand impacting on my face,
or having no
verbal
communication until she chills out a bit...or all of
the
above!
