Because reading a radio signal from the chip was too easy?
We chose to put AI on a doggie door. Not because it is easy, but because it is hard.
Do those exist? Does seem like an obvious option.
Yes, they are really cheap and the law (here in Sweden at least) requires all outdoor cats to be chipped. So the cat is probably already chipped anyway.
Even if for some reason you didn't want to chip your cat (you should absolutely chip your cats and dogs) it would be trivial to just put a tiny receiver in something that dangles off their collar for the door to communicate with.
Why should you? As a non-cat owner, I am curious about the privacy implecations of it. Also the benefits.
You store your contact information on the chip. Then, if your pet gets out and someone finds it they can take it to the vet to have the chip read. Then they can contact you and give you your pet back.
You could, of course, have your contact details on their collar. But collars can come off or break. And if you're worried about privacy, literally anyone can just read the tag on your pet's collar. Most people aren't going to have the equipment on hand to read a chip.
Are they RFID?
They have existed about as long as RFID has been available.
I had one about 10 years ago
Personally don't want to leave collars on my cats, I also don't let them outside much though beyond our patio.
Microchip bro, it's under their skin all pets should have them. Even if they are an indoor pet
Chips are implants that go under the skin. Most civilized places require pets to have them in urban places.
Ah gotcha, they are chipped in that way, I didn't realize you could just use that though for this type of situation. I definitely thought of the chips in the collars lol.
