By now I am sure you have seen a QR code or two. They are those funny looking squares of dots like the one shown here that can direct a properly equipped smart phone to a specific web site. You most often find them on business cards. I am intrigued by QR codes. They seem to have great potential however I have not yet seen anyone using them extremely well.
However I was impressed with how dental social media expert Jason Lipscombe has used them. Rather than put them on a business card Dr. Lipscombe has put them up as great big poster sized images in the windows of his office. The idea is that interested passersby will notice them and if inclined scan them to learn about the office on their smart phone.
