I like that it's super easy for customers because they don't have to wait around in line or be distracted by other people when scanning products at an aisle scanner, which has always been my biggest pet peeve about grocery store checkout lines! It really helps keep up with inventory since we can track everything going into our store from the point of sale system all the way back through our warehouse without having to physically go there - no more last minute trips home to check if anything was ordered incorrectly! We also use this tool to get feedback from our customers as well so we are able to make changes where necessary!
