SureFlap microchip cat door — Joule's first pet IoT

“I keep calling it Joule's first IoT device. It isn't, really. There's no network in it anywhere — no Wi-Fi, no app, no cloud, no second device to talk to. It's a battery, a coil, and a latch that knows one number. That's the honest description, and it's the most interesting thing about it.”

Joule arrives — what a pet microchip actually is

“A microchip doesn't find a lost pet. It identifies a found one. No battery, no GPS, no range past a few centimeters — the chip just answers one question, and only when something else asks it.”
