Of the many bar code scanners available for Android, the simply named Barcode Scanner makes a good starting place, especially for new Android users. With it, you're at liberty to scan QR codes to download Android apps, add a contact to your phone, or jump to a Web link. The scanner also reads retail bar codes, triggering a Google search for whichever product comes up. Though Barcode Scanner isn't as precise as other shopping apps that follow up their scan with a database search on where to find the item, it does its duty as a simple, multipurpose scanning app.
