Article written by the CEO of Neomedia one of the 2 biggest QR vendors in the USA
All i can say is wow i hope someone is given the opportunity to write an alternative view in response to correct the many "slightly inconsistent" points made by this article.
Some are correct but some are just plain old false.
As you know i dont have a "dog in this fight" and no commercial reason to disagree but a statement like "QR code size may also be physically larger in direct implementations" is just plain misleading.
Everyone knows it's related to the number of characters in a URL eg http://ACME.com/XYZ123 is just as good as http://NEOM.com/XYZ123
It's crap like this that gives vendors a bad name.
