At Carnegie Mellon, the scientists who’ve pioneered the discipline work not in a lab but upstairs in a wing that looks no different from most universities’ English or history departments. Look closer, though, and you’ll see signs that this is no ordinary place. The doors are all marked with 2-D bar codes; a professor enters his office by snapping a photo with his cell phone. Click! goes the phone; thunk! slides the bolt. It’s more secure than a physical key, which can be stolen and copied, and no less handy.
