I've heard of banks that had such files on all employees. In the event the employee needed to be identified, say a hostage situation, LEO would have a visual on the employee. This can be helpful if the perp switches places with them. Emergency contact info could also be in the same file.
I must say though, when I read comments that this is being done because its always been done and nobody knows why, maybe it's time to ask "why" and consider the stopping unless there is a good answer.
