QR Codes are becoming more pervasive in everyday life. I find them in magazines, on posters, event on billboards. So what is a QR Code?
A QR Code (which stands for Quick Response) enables the encoding of information into a scannable barcode. Very similar to how your grocery items are scanned at a cash register, a QR Code can store information so that anyone with a scanner (in this case, a smartphone or tablet) can access it. Codes can store text, hyperlinks (urls), email addresses, even an electronic business card (vcard format). There are many other options, but those are good ones to get you started.
The easiest way to play around with codes is to visit a website that generates QR codes. If you do a Google search, you can easily find one or two sites that will do this for free. Generally, these sites will let you select the format, edit the information, and generate the code. This one, for example, takes you to this website.
So why use QR codes?
QR codes offer a great method for getting data across mediums easily and quickly. Think about the following scenario: you mail a card to your customers (or family) with instructions to visit your website for more information. Instead of remembering the url and entering it into the device, the individual grabs their device, captures the code and is transported to the exact website (without any chance for input error).
This is just one of many ways to utilize QR codes. Some other ways that I’ve used include putting a code in a powerpoint presentation to allow audience members to view a document or website. Adding a QR code to a business card to allow easy transfer of your information into the individual’s contacts (remember that vcard format from earlier?). Whatever you decide to use these codes for, have fun and experiment!
