Barcode Scanner

One of the easiest ways to install an Android app is to use Barcode Scanner, a handy and efficient tool developed by ZXing Team.  Barcode Scanner lets you use your device's built-in camera to scan a Quick Response (QR) Code containing an app identifier, like the ones you see in this article. In a few seconds after scanning, it decodes the QR code. You just need to press the "Open in browser" button, and the app is ready for you to install—much quicker than typing out the app's name to search with the Market app. The Google Play website now allows you to press the 'Install' button in your PC's browser to install an app to your mobile device... but to do so you must be signed in to your Gmail account associated with the device. The Barcode Scanner saves you this hassle. Barcode Scanner also allows you to scan and share other information such as contacts, bookmarks or text messages via a QR Code. A must-have tool, and it's small in size.
