It only took about three months, but I finally found one, a print advertisement from Microsoft which features one of their own Tags.
Another item that I noticed, in the instructions to download the reader app it says "phone" not "smart phone," and I wonder why the ad is not as specific as it should or needs to be. As far as I know, 2D barcodes can only be read by smart phones, so why doesn't Microsoft make the distinction? For readers who own a non-smart phone and attempt to download the app and scan the code, what kind of experience will they end up having? A lousy one, that's what. Is Microsoft comfortable with this?
For a company that has spent a lot of time, money and resources to develop and promote their own proprietary 2D barcode platform (i.e., Tag), all of this comes as a surprise, and I wonder what the company's true objectives are for this advertisement. I certainly don't get a sense that Microsoft is looking to take the time to inform and educate consumers about 2D barcodes, let alone Tags. Perhaps Microsoft just assumes that people already know about 2D barcodes and there is no need to inform and educate.
