What are barcode apps?

Bar code apps are applications for a mobile device that let the user check prices and information about different items by scanning the items. Bar code apps typically reward users for using the app by giving loyalty points, which can be redeemed for cash or gift cards.

Bar code apps are useful for comparing prices at different stores without having to physically travel to each location. Many offer an online look-up option that can be used to see online prices, as well as to see reviews written by users. Certain apps also contain a price watch feature that lets users monitor items on their wish lists, as well as a price change section that shows recent price changes.
