Physical and file system access-control merging?

I was trolling through my daily news feed when I ran across this article on SecureIDNews. Its about a company which is marketing a card which controls access to both physical spaces and computers. I found this an interesting article since my research focuses on ethnographic studies of both physical and logical access-control administration. As a researcher I continuously get criticism from the computer security community that physical access control is a solved problem that has nothing to do with them. I’m glad to see someone interested in merging control of the two systems and am interested in how the merger will go.
