When an item is sold, its weight is written in four places: on the barcode tag, on the weighing-scale slip stuck beside the tag, on the rough estimate, and on the final bill. This screen puts them side by side and flags any entry where they do not agree — so a wrong item, a swapped tag or a typing mistake is caught the same day.
