The only thing I could add, to follow up on what Robert just said, is that we don't do anything at the moment to capture any kind of biometric, and really it's a simple process. Someone has to cooperatively look at a camera, let's say, to capture a simple image, which everyone knows how to do. It's simpler than a fingerprint. A fingerprint's the next step, maybe, but even just to capture a facial image....
As Bob mentioned in his remarks, there is a camera currently at every immigration desk. It's not being used to capture faces; it's more just to surveil the area.
So there are some simple things that can be done to take a big step in enhancing the feasibility of biometrics.
