If you are not using QR Codes you are crazy. First, in case you live under a rock, A QR code is a barcode readable by scanners. 85% or more of the phones being sold today have the ability to scan QR Codes.
Here is the beauty of QR Codes. Within that code in the bar, information is stored. Here are some examples of information that can be stored. This information is unlocked and displayed to the user.
URL’s – Send them to your facebook page, your website, your listing detail page, your virtual tour, a youtube video, or any other URL you can imagine. Ideally, since they will probably be viewing it on their phone’s browser, send them to a mobile version of your site. If your company’s listing detail does not automatically create a mobile version use something like Vflyer to create a mobile flyer. Then send people to that mobile flyer.
Why would you put a piece of paper with a couple of pictures and some information out on a sign when you could literally give someone all of your contact information, community information, house information, pictures, virtual tours etc? I believe in the very near future no one will have paper flyers anymore. It may not be QR Codes but it will be some form of digital information.
Now, think of some creative ways that you can use QR codes to build your business. For my test, I just changed my profile picture on facebook to a QR Code. I then used goog.ly to shorten the url and track the number of times it is clicked. If you are not using goo.gl click here to read why you should. Hint, it creates QR Codes for you amongst other things.
google URL Shortener.
