How to Scan QR Codes in Android

A QR code is a barcode that a smartphone such as a Droid can read via its camera. This is useful in that you can find an app online such as Lightning Bug sleep clock, take a picture of the QR code with Barcode Scanner, and Android will take you to the app in the marketplace to download. Barcode Scanner comes with Android phones, so no need to download an app before doing this. And yes, you read that right: Use your camera phone to take a picture of a picture on the computer monitor. It's a literal 'screen shot'!

You can even make your own QR codes with a generator. Check out the QR code for Aeonian Samurai:
