Quite sorry for the stupid sounding question, but I don't know how else to describe it. I've seen it on a pack of gum and in a magazine. It says to take a picture of this square with a black and white digital looking pattern with your mobile phone. What is this and how does it work?|||That is called a QR code.
If equipped, software your phone locks onto the picture on the camera, and discerns the data in the code, and does something with it, such as go to the promotional website for it.|||Are you referring to the bar code (or the thing with the b%26amp;w squares all over...could be similar)? It's probably a tool that identifies the product and gives you information about it, based on the code you take a picture of.
