A QR code is the evolution of the barcode. It’s a 2D barcode that can represent an internet address, text or a phone number.
To read the QR code you need an app on your phone to scan the code.
You can install NeoReader for iPhone.
If you have an Android phone, look for Google Googles on the Android Market.
Open the app and scan the code by pressing the center button on the screen.
