Android 101: How To Scan / Use a QR Code

So maybe you've seen one of these square barcodes that have a bunch of dots in them somewhere and wondered, "What the hell is that mess?" Well, that mess is called a QR code, which stands for Quick Reference Code. A QR code is basically a barcode like you find on any product you purchase but instead of bringing up a product number when scanned, it can bring up a lot of different information (i.e. a website, or even a command for your device to head to the Market to show you an app to download). Unlike a regular barcode, these cannot be scanned with a straight red line in your camera's viewfinder (like you may see in other barcode scanning apps), it needs a special program to scan it. In this Android 101, we show you how to scan a QR code using a special QR scanning app. Check out the video above for more details and feel free to leave any comments or questions on our site:
