I started working on a project with a friend to use NFC in phones to start on this problem. We where working on using NFC to auto lock and unlock your PC when you phone was on your desk hear a receiver. The idea originated from using the NFC to by pass the RFID door scanner so we didn't need our toggles to get into the office. Deciding we could get in troupe pissing around trying to bypass the security system we ended up working backwards to something easier... being the lock/unlock thing. Unfortunately we stopped working on it when my friend went broke and his priorities changed (i.e. silly hobby projects don't pay the bills). Would love to pick it up again some time in the future, we had lots of awesome discussions and ideas with this field. We where just investigating a braclet RFID to add to the system as a two factor authentication, so you needed more than just the phone do it. But thats roughly where we got up to.
