QR Code or Quick Response Code is a two-dimension matrix code developed in the mid 90’s in Japan. Businesses are drawn to it because it offers an improvement over barcodes. Wisegeek explains, “QR Code contains data in both vertical and horizontal directions, whereas a bar code has only one direction of data, usually the vertical one. QR Code can also correspondingly hold more information. QR Code is easily digested by scanning equipment, and because it has potentially twice the amount of data as bar code, it can increase the effectiveness of such scanning. QR Code can handle alphanumeric character, symbol, binary, and other kinds of code. QR Code can hold up to 7,089 characters in a single symbol. ”
QR Code has become increasingly popular with the use of cell phones. I recommend checking out an article by Searchengineland.com to see some video demonstrations. A code can easily be generated on sites like Kaywa.com. If you are wondering if search engines like Google will be able to recognize them, “If you add them to your website, the search engines will see that your pages have changed, and that you are updating pages. The search engine will see a new image and index it accordingly. At some point soon, the search engines will likely recognize QR codes and possibly index the content in them.”
There are several recommended uses for the QR Code but one that I found to be interesting was that you could add one to your business card. People would then be able to scan your information directly into their cell phone contact database.
Some other recommended uses may be to add them to media ads. This simple little code could communicate product, contact, offer, and event information as well as coupons and social media links.
