From time to time at AndroidCentral you’ll see bar codes like the one above. Actually, it’s not a bar code. It’s called a QRÂ code, and it’s used as a shortcut to link to content online using your phone’s camera, saving you from typing lengthy addresses into your mobile browser.
You’ll need an app that can read QR codes (we like Barcode Reader or Google Goggles in the Android Market). When you see a QR code in an app review, hit it with the barcode reader and it will take you to the download section in the Android Market. It’s that simple.
Go ahead and try it on the code above. Our treat. :)
