So... the brighty "researchers" at Microsoft finally heard of QR Code, maybe suggested that a decoder be implemented in a next release of Windows Mobile, and had to reinvent the wheel so it would be "new stuff" ?
That said, it *is* different from QR Code, a QR Code can story any arbitrary data, this variant seem to resolve around URLs to web services that do an awful lot of stuff without the user's explicit consent (other than scanning the code). Damn. Having seen the horrors of ActiveX "automations", it sure don't want this in cellphones!
Maybe I sound like an party-pooper, but wouldn't color complicate the whole stuff? I mean, a QR code or a standard barcode can be printed in a black-and-white newspaper page (which are not *that* uncommon), this Microsoft Tag could not.
