Do these things piss you off? Do you even know what they are? Do you know what they are used for? What you see here is a QR Code.
Wikipedia defines a QR code: A QR code (abbreviated from Quick Response code) is a type of matrix barcode (or two-dimensional code) first designed for the automotive industry. More recently, the system has become popular outside of the industry due to its fast readability and comparatively large storage capacity.
Whatever that means?
You see these things in stores and in magazines as part of advertisements. You need to download a QR Reader on your smart phone to "read" the QR Code. When you take a picture of the QR Code you immediately get product information or, better yet, a coupon for the product.
I think these things are ugly...and I can not imagine that an Ad-Man wants to stick this QR Code on their beautiful advertisement campaign for say, Ralph Lauren. And, who really wants to deal with taking a picture of the QR Code? Why not just offer a coupon to the every customer? IMHO, I do not think these things have really caught on, and I really do not see them catching on...in a chage the marketplace sense!
No question that they are making a big push...but I hope they fall by the way of the Pet Rock!
