I've noticed several of my friends on Facebook updating their profile images to something that looks like the above image. What this means, mostly, is that a lot of my friends are total geeks (in a good way). The above is a copy of a "QR Code," which is a bar-coded URL address, in this case, for the WebRevelation.com website. Someone who has a QR reader app on their phone can scan the above image, and be taken to the website. The QR codes can also contain videos, multi-media presentations, contacts info, maps, etc.
Right now, this is a little bit gimmicky in the U.S., because most people don't yet know what to do with the codes, but businesses that cater to the younger demographic, or to an international customer base (like hotels and restaurants) will want to learn how to use these. Eventually, if the trend continues, these codes will be a handy way to quickly exchange information with and among local businesses.
If you want to try out the codes, use your smart phone to go to your mobile provider's marketplace, and download highly-recommended free app for QR codes, like QR Droid. Once you've downloaded the app, you can create the bar codes, or read them with your camera. You can also generate the codes using a free service online from your laptop or PC such as QuikQR.com.
