I prefer this as my QR code reference: http://picturesofpeoplescanningqrcodes.tumblr.com/
And yet the QR code on the front page has an embedded logo, which isn't at all part of the spec, I think. Kind of ironic. I know brands love those designer QR codes (or at least loathe them less) but they have a significant impact on scan-ability, even if many decoders are good enough to scan them, they might take longer, especially on non-top-of-the-line phones. The point of a QR code is to make that information easier to get at, and the designer codes are at odds with this. (disclaimer, I worked at a barcode startup for a bit, and I left partly because I don't buy QR codes)
Licencing - you've misspelled 'patented' Readability - "its", not "it's"
There's a bunch of other grammar/style issues - get someone to proofread it.
>Would you do it? Always try to stand in a shoes of a regular person and ask yourself would I scan it? Does this convince me to take out my phone and spend 10 seconds of my time to scan that QR code? Is it attractive enough?
When the answer to this question is a 'No I would not', I fail to see the utility of these things.
And I still see companies placing QR codes on billboards on the highway!
How many people that aren't in the tech scene actually know a simple way to scan a QR code?
> Some places are better than others for placing QR codes. Bearing in mind it takes a while to scan, rather than putting a code in that busy passage way why not put in on the subway train where everybody is rather bored and is playing with their phones anyways.
Because there is no reception underground. (Yes, this is changing, depending on the city. e.g. in London there is now free wifi at some stations, but not between stations.)
Also, some people, when a stranger takes a photo of the ad above their head, will mistakenly believe the stranger is taking a photo of them, and treat it as threatening behaviour.
There is a typo in your <title>: "aobut" should be "about".
