If you haven't seen these things yet, go ahead and learn what they are and how to use them, because they are the next big thing. These two-dimensional barcodes can be read by a number of devices, but most importantly smart phones like the iPhone and Blackberry. A phone can quickly scan the QR Code (QR = Quick Response) with its internal camera, and that might translate into plain text or take the phone's web browser directly to a URL.

Why is this so important? For one, these square-shaped QR Codes are going to start showing up everywhere. Two, they are free to use and store a LOT more data than the typical bar code. Three, they can be used in so many different ways. Imagine watching a commercial and seeing a QR Code in the bottom corner of your TV. While watching, you might let your phone scan the code from where you're sitting and it could take your phone's browser to a web page with more information about the product, or directly to a screen to buy what you just saw. Or the QR Code could automatically have your phone call a certain number. No typing, just a quick scan and you're off. There are probably hundreds if not thousands of different applications for these things and ease of use and probable adoption by many industries will make it as common as displaying a phone number in the years to come.
