Google showed off on December 7 a prototype of its mobile tagging technology. The company is “QR” barcodes to more than 100,000 local businesses in the U.S. Mobile users can snap a picture of the bar codes and obtain information about that business — including reviews, coupons, and other information. (Smartphone users need an app on their phones that can read the QR codes.)
In January 2009, Microsoft launched a beta of its own bar-code search technology, known as Microsoft Tag. It also introduced a free mobile tag reader. Microsoft, being Microsoft, couldn’t simply rely on the QR standard. Instead, it announed it was creating its own bar code technology that stores more information, more dynamically, offering more user choice. It’s cool that Microsoft Tag allows developers to determine the content and experience users will have by allowing choices of text, video, maps, discounts, promotions. But the lack of QR support is a deal breaker for some.
