 If you look at the display and you're worried about there might be a skimmer or they've gotten into the machine somehow, they showed me how that's done and the precautions that are taken. He says if you look up on the display, you'll see on the bottom left-hand corner somewhere on the left a lock. I noticed that. That indicates I had not. And he showed me. It's just a little lock. He says that means this machine has not been tampered with.
