The US Department of Homeland security is going to start requiring foreigners to carry a “card” with them at all times. It will be an RFID type of card that can be read from 20 feet away.

Anyway… I don’t care a whole lot about that and the whole privacy concerns (I’ll let the privacy activists deal with that). But, it would be a neat technology to use for my house that I’m going to be building soon.

Maybe a card you carry in your wallet or something could automatically unlock the front door as you approach the door or something. Has anyone seen or heard of a company doing any RFID stuff for the home?
