I worked in a place in 2006 where my username was a badge and my password was my fingerprint. The badge had to be inserted into a reader for the computer to be unlocked. It was also attached (via a badge holder) to the RFID badge needed to open any locked doors. This meant that to get to and go to the washroom, I had to take my badge out, which locked the computer. It was a very neat and secure system.
