MS is doing their own app, and it's listed as coming soon. Soon after everyone else I expect.
Doubt you'll get much more support than that for a tagging technology that competes with QR code unless there is a reason to integrate this proprietary solution into Android apps that do useful things with tags. For now, all you really need is a scanner that can convert the tag into a URL and open a browser. The rest of it is just chest beating.
