They come to us from Japan where they are very common. QR is short for Quick Response (they can be read quickly by a cell phone). They are used to take a piece of information from a transitory media and put it in to your cell phone. You may soon see QR Codes in a magazine advert, on a billboard, a web page or even on someone’s t-shirt. Once it is in your cell phone, it may give you details about that business (allowing users to search for nearby locations), or details about the person wearing the t-shirt, show you a URL which you can click to see a trailer for a movie, or it may give you a coupon which you can use in a local outlet.
The reason why they are more useful than a standard barcode is that they can store (and digitally present) much more data, including url links, geo coordinates, and text. The other key feature of QR Codes is that instead of requiring a chunky hand-held scanner to scan them, many modern cell phones can scan them. The full Wikipedia description is here.
How does the cell phone read the code?
The cell phone needs a QR code reader, like this one from Kaywa. It takes literally 1 minute for someone with an iPhone or Android phone to find and install the reader.
How do you generate a code?
You can easily generate a QR code using a site like Kaywa.com or you can use the Open Source code to generate codes for you if you have a smart developer on hand. Google also has a tool — see our separate article about that:Close-Up With Google’s New QR Code Generator.
How can you use QR codes to benefit search marketing?
We are only just scratching the surface of how they will be used. We have added one to every business listing in our directory. Here are a few examples of how others are using them.
