RFID Enables a Secure Zone Around Your House

Weight sensors around your house know if there are people there. Then, those permitted to be there must carry some form of ID that will allow your home to know that they were there. They could have the ID on their key chains, jewellry, wherever they want. This way, you'll know about everyone who got to within striking or stealing distance - the postal worker, the man from the power company. And if they don't have the RFID - people will be notified and cameras will do their best to get a good description.
