Our cat has a Tracer RFID microchip. I see there are new a number of cat flaps on the market that read your pet's chip, so stop other cats from getting in, for example:
Has anyone tried making their own RFID reader?
Thought it might be fun to have some stats about when our cat goes in and out of the house!
(might be easier/cheaper ways of doing it!)
As part of some animal welfare work my research group does with Biological sciences I have looked into using social media to improve the relationship between us and our companion animals. I used an RFID tag (Phidgets) on my cat when it eats(receiver at feeding area) as we were worried about him while away from home (specifically his eating behaviours), some more info here: http://www.derekfoster.net/?p=460 . Basically he tweets when he eats :) follow him on Twitter @marjwark . Currently looking at more ways in which to use RFID tags for increased animal welfare.
Thanks for your email Derek - really fun project :)
Our of interest, how close does your cat have to get to the reader?

I haven't seen that type for sale - the two cheaper types that I have seen are magnet base (which stops stray cats coming into the house):
And infrared based:

There seem to be quite a few on the market now.

Our cat, Boris, has a Bayer / Datamars / Petlog based identification microchip.
