I doubt the robot can match up the product with the tags the bar codes on the product are on the side back or bottom of the package. Plus WF cant get any technology to work well since we use programs that are in house made. I wouldn't worry about it until they do a massive overhaul of all systems and invest a ton of money into it which I think is pretty unlikely.
