IIRC It's quite large in diameter around 25 to 30mm I think, but only 1mm
or
so thick

I'll try and remember to check tonight

David,
can you remember what size the thin PCB disc is inside
the keyfob? I presume it is mostly a coiled aerial. I am hoping
to get a tag small enough to be carried by our cat because a)
the Staywell cat flap key is large and awkward shaped, and b)
it doesn't have a very good detection range, especially from
outside. Mounting an RFID reader aerial just below the door on
the outside would seem to give a closer range.

Yup,  those are the ones I have

his site is http://home.btconnect.com/QTEKNOLOGY/
for more info

If I remeber correctly the keyfobs come apart easily and inside
is a very
thin PCB disc with the RFID IC embedded in it.

FWIW I The reader sputs out serial data in the of the Animal ID
tags in our
cats,  now I just need to get Cat, Reader, DSO or PC together
in the same
place to work out the code
hmmmm I wonder If pronto could store the code If I modulated the
bitstream?.....

I think this is going to turn out to be one of those projects
that requires
a whole box of 'Scooby Snacks' :-S
