You may have seen these strange-looking boxes popping up more and more in magazines, and newspapers, web sites, business cards, signs and retail store displays. They are called QR codes, which stands for “Quick Response”.

While they may seem like a new invention, QR codes have actually been around since 1994, primarily used in Asia and Japan, where they were invented.

QR codes allow a smart phone user to scan the code with an app installed on their phone – Red Laser is our app of choice – and be given an option to view a specified URL or save contact information embedded in the code. This frees the user from having to manually type in a web site address or contact information, which makes them more likely to view the information embedded in the code.

Another part of the QR code’s allure is the mystery of what’s behind the code. Will it be a video, photo, web site or someone’s contact information? Scan the code to find out!

In addition to scanning QR codes, Red Laser also allows you to create your own free QR code which you can email to a recipient (or yourself) and/or save to your phone’s image library for later use. In addition to its QR code functionality, the app also gives you the option to scan bar codes on products and view price comparisons online.

Contrary to popular belief, QR codes need not be all black and can even be dressed up with a logo and other custom design elements – within certain parameters.

All in all, QR codes can be quite handy for a number of reasons. Have you seen QR codes used in a creative way? Share your story with our readers by leaving a comment below.
