QR codes are huge right now. If you aren't familiar with QR codes, they are basically a 3D barcode that can be scanned by cameras in smart phones. The image to the right is an example of one (it actually works by the way):
If you have a smart phone (and it has a camera), you should be able to download a QR Code reader. Once you have the reader, you just point it at a QR code, and whatever is contained in the QR code (web address, video, telephone number, location, etc.) will show up directly on your phone.
QR codes have caught on because they are so convenient and once you know what they are, you'll probably notice them lots of places.
Now that you know a little bit about QR codes, you might be wondering how you can make one. There are plenty of websites and smart phone apps to do so. This week I'll just mention qrstuff.com. It was suggested in a conference that I attended, and its pretty cool.
It gives you different options for what you can put into your QR code, and also lets you change the color, for free! The reason its free is because they have products you can purchase if you so choose. But, it isn't difficult to use the free tool, the ads aren't obnoxious, and it works really well. Also, the site talks about where QR codes came from, and how they are created.
