We're excited to announce that Google Product Search for Mobile recently launched
barcode scanning on Android devices. In order for your product offer to be listed when a user searches using their barcode scanner, you need to include a unique product identifier attribute like a Universal Product Code (UPC) or European Article Number (EAN) in your data feed. For more information on unique product identifier attributes, please see
this article in the Google Base Help Center.
