Plexidoor just anounced a new sliding dog door. It works with an RFID chip (like a ton of dogs have now), when the dog gets close the door slides open. Doesn’t work for other dogs…. Hmm brilliant?
Personally I don’t like the idea of a dog going in/out on their own. I personally don’t like tons of mud everything, so unless the system could be disabled in the rain…
Now a better idea? Put one of those RFID chips on your key chain, you walk to your front door, it automatically unlocks, shut the door and walk away, it automatically locks. Now there is a good idea! Your door is always locked, except for you, in which case its always unlocked!
