This needs a QR code sticker. http://qr.kaywa.com/?s=8&d=http%3A%2F%2Fpicturesofpeople...

I chuckle every time I see this.

But good sir, it's empty!

This will never stop being funny

My 6 year old daughter is absolutely fascinated by QR codes. I've been nagged into scanning ones on posters, in magazines, and even one that showed up in the middle of a TV show...

I have a six year old son with this same fascination. Sometimes I'll walk into my home office and find some mailer with a QR code sitting there waiting for me. His inquisitive mind just has to know what the phone will do with the code.

You can pick up barcode battlers on ebay for cheap. Although they're probably antiques now.

I've got some somewhere, but I don't think they did QR codes and they certainly didn't launch a link - that's what she enjoys. No idea why, but I'm not going to discourage her from anything that gets her interested in technology. We're going to get a t-shirt printed for her with a QR code saying "If found, please ring [phone number]".

First thought: this might be a neat Android game Second thought: this has already been implemented

(by the way, this displays in an awful Spanish for me, because of my default language)

I do mountain bike (and thus indirectly hiking) trail development, construction, and maintenance as volunteer work. This has shown me a surprisingly useful place for QR codes: on trailhead map boards. The code just links to a (well optimized) PDF of the map itself, along with some text that says "Scan this with your phone to download a copy of the map.".

It amazes me how many people I see scanning the QR code to get a copy of the map before they head out on the trails.

Every Android phone in Japan would be wiped out in a matter of hours. I see people scanning them in Tokyo constantly.

I actually found them quite useful as a bookmarking tool when comparison shopping appliances at retail stores. They usually had code to the retailer's page for the appliance, and another for the manufacturer's page.
