DONT Smile for the Camera

When I got my last government ID, I was shocked that they wouldn't let me smile for the picture.   A recent article on MSNBC reported that Virginia drivers are also restricted from showing their smiles on their licenses.  After looking it up, I learned that this is to make pictures more compatible to face-recognition software that, although it is constantly improving, still requires smile-less expressions to make an identification.  Even without smiling, I just don't know how reliable this software would be for the applications they intend to use it for.  Interesting stuff...
