Google’s hoping to spurn more interest in their newspaper advertising service – Google Print – by adding bar codes to ads. If you have a cell phone that is compatible, you could point it at the bar code and go to a web site printed at the bottom of an ad.
As an example, I’ll take my favorite section of the newspaper – Arts and Entertainment. If you read a review about a performance of Wicked in your area, there may be an ad for the production. If it was a Google Print ad that used bar codes, you could quickly access the right page to buy a ticket at a nearby theater. The barrier at first will be just making sure you have a compatible phone, with Internet access, and the right software installed.
