Not sure who authored this article, which appears on Mobile Commerce Press, but let's get one thing straight: the SnapTag code developed and marketed by SpyderLynk is not a QR Code. SnapTag is a proprietary two-dimensional code format that offers some of the same functionality and works in a similar manner as does a QR Code, but it is not a QR Code.
Also, digging a bit deeper than the article, how confusing is this? When I search on the term "snaptag" this is one of the results I get:
QR Codes for Business : QR Tags With a Code Ring : SnapTags (this is the title of the landing page)
Get unique QR codes for business marketing with cutting-edge SnapTags. These eye-catching QR tags combine your company logo with a unique code ring.
If a SnapTag is a proprietary code technology, why is there any need, or interest, in referring to QR Code technology? And, why is the term QR Tag used to make it sound like QR technology is part of SnapTag when, in fact, it isn't?
