Their actual names are QR Codes, like the one to the left. They seem to be cropping up all over the place, including lawyers business cards.

I’m not sure about the benefits other than being a gimmick to attract attention. I posted as much this week on twitter and this led to a brief twitter conversation with @jeffrey_brandt, @emmalouwillcox, @KMHobbie and @geekchicy on the merits of QR Codes.

Some of the comments raised were:

• scan code smartphone, no typing – big advantage! Great for location based stuff (Maps)
• why should you need an app for it?!
• QR code on google.gl service link page, e.g. http://goo.gl/info/7nKy1#week
• I see biggest potential value of linking static hard copy to dynamic web content

I was also reminded of Microsoft’s attempt at its own version (as somebody pointed out “came up w/their own version of QR code. Quite silly!”), this then reminded me I did a blog post about Microsoft’s “Tag” just over a couple of years ago!

“Microsoft Tag – perfect for the paper file?”

I re-read my article and can’t help think now that a simple barcode would be as useful and so my thoughts come back to my original point made on twitter:

Are QR codes just a fad? What are benefits over urls? Seems bit of a gimmick to use an app to snap QR to get a link? Am I missing something?

And I don’t seem to be the only one, Google seems to be thinking the same. But I am going to install a QR application on my Windows Phone 7 and give it a go for a while. I’ll post what I think in the comments, but let me hear your thoughts on QR codes too.
