I believe the perfect tool is a calculator to simply scan an item and value it instantly. It could be the ideal item for people who want to collect and buy stuff and worry that they are getting scammed for it. It could predict if the item is worth or worthless and prevent losses and should be something that high-end collectors could deeply rely on. It could also scan simple items such as maybe groceries which can also help you get your money’s worth and avoid immense overcharges on items
