CNet showcases Microsoft Tag, a nouveau QR code for traditional media publishers and products. Most QR code systems, including Microsoft Tag, require a download of software that can read the 2D barcode. On smartphones this is not the problem it once was. New market entrant JagTag doesn't require specialized software.
Microsoft Tag works with feature phones that have a camera as well.
There are lots of companies in this 2D barcode space and lots of proprietary formats. Standardization would push the whole industry forward. Microsoft may have success with Tag because it's, well, Microsoft. Companies such as Geovector and NeoMedia have patents in this area and we'll probably see litigation eventually.
Putting all that aside, this phenomenon of "hyperlinking the real world," is going to be massive -- capital M. Phenomena like SMS marketing and QR codes/Tag proliferation could actually move much faster than "mobile advertising" overall. Because they help measure consumer response as well as make traditional advertising more dynamic -- you can put anything you want behind a Tag including video, websites or coupons -- industry and publishers will adopt these technologies in the very near term. Indeed, they already are.
People and most industry observers don't realize how pervasive this will be in say three years, provided that there's some standardization that helps remove uncertainty over which system to use. Consumers are already using traditional barcode readers in stores to get price and reviews information. I've both done this and witnessed this extensively (over the past Xmas shopping season).
Imagine a code/Tag on every product, in stores on displays, on TV, in newspapers and magazines, vending machines, yellow pages directories, outdoor ads (e.g., movie posters). These codes will be absolutely everywhere. It's just a matter of time.
As a side note, we're also likely to see 2D barcodes integrated into location gaming in the very near future . . .
