From JSharkey’s Android Scan: “Scan is an Android application that finds pricing and metadata for anything with a barcode…Just point your phone at a barcode and scan it.” What happens next is pretty damn cool, but the game changer aspect is that it shows you the price of the item as sold by various virtual and brick & mortar stores. For example, if you’re looking a book in Barnes & Noble, and scan the barcode with your Android phone, you’ll see if the Borders down the street is selling it for cheaper, or if there’s someone selling it used on Amazon for 36¢. You’ll also be able to read reviews of the book/product, and if it’s a CD (who buys CDs?), you’ll even be able to download 30-second samples of each track. Buyer beware? With Android Scan, not anymore.
