Why are they different?

If the language is the same, and the text link is the same then why are the QR-Codes Different?

I am convinced that QR-Codes are passing on more information than you realize.

While some may say that it is simply a generator difference, I am not convinced.  Each QR-Code is readable by quickmark, and apparently contains the exact same URL.  But when generating a new QR-Code from existing QR- codes the offspring is unique.  So the only conclusion we do have is that the generators are marking the code by who generated it, and subsequently the quickmark generator is passing on something from the first generator. …So far the time stamp theory has proven negative.

The text link generated by this QR-Code is : http://google.com/m/place?georestrict=input_srcid%3A6a8383041e7e4ce8 according to QuickMark (Big mama).  Quickmark then provides an option to re-create this QR-Code….

Yes… they are different… but they carry the same url.  So Big Daddy and Big Momma are produced a new baby.

Here is Big Mama’s DNA of the same text/link as generated by big quickmark on direct input:

Different.

So lets test the text link with an online generator… Number one in the SERP for QR-Code Generator was.. qrcode.kaywa.com

QR-Code generatede by Quick Mark of Google's QR-Code

QR-Code generated qrcode.kaywa.com by of Google's QR-Code

No surprise at this point but this is….. Different.

And now if you scan qrcode.kaywa.com (sample #1) with #QuickMark and hit the create button…

Summary

While the intended information is the same, link/text, the QR-Codes are clearly different based on how they are generated.  It seems to me that they must be passing on additional information.  To what end or what information I cannot say.  I am not going to accuse quickmark as being the mother of all whores or Google as being the anti-christ.  Although it is amusing that if this were true.. quick “Mark” could easily be the “Mark of the Beast” if google, which is a number, is indeed the “Beast”.  How many zeros in a google???  Was that 666??? Just kidding!

Feed the beast!

Can someone give me a viable explanation as to why these QR-Codes are different?  What information is being passed on?
