I said three days ago that Apple’s Pay could change everything, and it certainly has the potential to change the way we pay via smartphone. Now here’s another device that could change the way we pay.

You know that plastic bar that you use in the grocery store? The one that blocks other person’s load of groceries so you don’t pay for his or her stuff? Well, imagine that but with animated ads. The ads will only show up so it will play if they are on the conveyor belt. I guess that will save the battery life.

So I am a little confused. What kind of ad could possibly make me buy anything else unless the item is right in front of me? There had better be an ad for gum or something. Maybe for a tabloid magazine?
