Dog Doors - Finally, a perfect use for RFID!

Radio-Frequency Identification (RFID) has been "the wave of the future," at least to designers, for quite some time now. The problem is, that future seems annoyingly slow in coming - you know, along with stuff like flying cars and teleportation. Well, here's one application of RFID that's been deployed in a commercially available product, and put to excellent use. Plexidor dog doors use RFID tags on your dogs' collars to cue the door to open. Think of it like a garage door opener, but the pooch doesn't even have to push any buttons; the mere proximity of the RFID tag does the trick (ha). This keeps out strays, thieves, and the neighbor's darn dog, while allowing your dog to enjoy all the indecisiveness he or she needs regarding indoor/outdoor conundrum - which in turn allows you the happy pet owner to remain firmly planted on your rear. The future is here, and it is lazy!
