Hmmm…. I am sure that you have seen either of these two new codes (QR & Microsoft tags/codes explained on Joseph Kim’s blog)especially if you read any current magazines. 

UPC codes has been around for awhile and for years, people in marketing has been trying to make it useful for the consumer. In the late 90’s Radio Shack pushed the cuecat to help consumers to scan products to go to the vendor’s website. Unfortunately, this concept did not materialize to anything the average person would really want to do.

However, in the past few years, vendors have been experimenting with the usage of QR codes on smart phones as demonstrated in the image below. I am sure that the usage mobile tags will continue to grow in this smartphone age.
