Barcodes have been a staple of the retail business for years, and have found their way into other industries such as publishing, shipping, and postal services. Some are now being used online to act as quick references to websites. Most of the online barcodes are of the 2D variety rather than the traditional vertical bar sequence, but they perform the same function... providing information in a graphical format that can be reliably interpreted by a computer.
Barcode Scanner is an Android app that allows you to snap a photo of the barcode with your Android device's camera. The app then interprets the barcode for you, displays the information contained in the graphical image, and offers to take additional steps such as open your web browser to display the URL contained in the barcode. You may begin to see these 2D barcodes in magazines and online more frequently, and adding the app to your Android is simple and can save you lots of keystrokes.
