Microsoft's Tag Reader is an app that allows you to scan a product's bar code using your phone's camera. Your phone will then give you information on the product including promotions, videos and special offers. This is the Redmond based firm's first application for Android and Tag Reader has already been released for the iPhone, Symbian, BlackBerry and of course, Windows Mobile platforms. The app is free and can be downloaded from the Android Market. If you Pre and Pixi users feel a bit left out, start bugging Microsoft and perhaps the next build will be for webOS.
