RFID and Twitter tell where your cats are

RFID and Twitter tell where your cats are


Ioan Ghip made this tweeting cat door with an RFID reader and some keychain tags attached to his cats’ collars. The door only lets the cats in (not the neighbor cats) and tweets which one is going in or out, complete with a picture. (Thanks, Matt!)

    I have been considering doing something similar to track our cats and their use of the facilities (litter box, water, food). We don’t make them wear collars because they are indoor cats, but they have those RFID chips under their skin in the back of their necks. Anyway, great project! I think I am inspired enough to prototype mine now.

    Just remember to have some visible ID on your cat so Animal Services can get in touch with you when your cat gets run over.

    What a great idea! I suppose you could also program the door to lock the kitty in or out should you need to.

    1st Cats, then people. The way the government is going it is only a matter of time. Got a mobile? Guess what!

    Neat. I thought about doing this and a buddy pointed out that we have a guy here in town that uses facial recognition software instead of RFID tags. The idea is to keep the cat out if it’s carrying half a dead mouse or some other nasty thing.
