I might be a bit naive, but I am wondering why the airlines didn't already do this sort of stuff. Wouldn't have to be embassing or anything, because cattle are weighed by walking onto a scale that is basically part of the floor. And the sell cattle by the pound. They don't have to stand still or anything, so basically, they could put this in the floor and measure weights of all the cargo and they walk onto the plane, then the pilot could have a total cargo weight before they depart.
