What? That's not how a lottery ticket machine works. Part of the front has to be scratched off to determine if it is a winner, even with the machine. I know, because I remember having to scratch this part off myself for customers redeeming tickets back when I sold them. (The part the machine needed was along the edge, and many didn't scratch there.) (This is specific to Tennessee, but I doubt any state used a system where you can tell if it's a winner without anything being scratched.)
