QR code add ons and widgets are popping up everywhere it seems. Though what people are actually doing with them I have no idea. Two "barcode" readers have been developed for Firefox: The Barcode 0.1.2 developed by Duncan Sample and James Carter, and the Mobile Barcoder by Geek Shadow.

 I've downloaded The Barcode 0.1.2 which when I roll over the word "Barcode" that now appears on the bottom left corner of my browser, a QR code appears, but really it is quite useless - I can't screen grab it to actually use anywhere else,  and I can't see what the point is. Perhaps its not working properly on my setup (MacBook Pro latest version of Firefox). I mean I'm hardly going to surf the internet on my mobile phone at the same time as on my laptop, so I don't get it.... I've not yet tried the Mobile Barcoder, but since it says its experimental and so far only 3 people have downloaded it. I don't think I've fallen behind the game yet...

Mobilebarco.de is a German company who have developed a wordpress QR widget and they've also created a facebook app, which I have just added to my account. It provides a QR code of your facebook profile, and displays it on your profile page, which of course is redundant since you are already there anyway. Though, at least with the facebook app, you can download the image from facebook and have a .png file to use with other media. I've set my privacy pretty high on facebook, and I wonder whether the QR code profile link is really that secure. I am thinking that it would have to be... surely...  but then again developers overlook the simplest things sometimes... shall test it and see.

 I'm sure there are more out there, so shall do some trawling and see what I come up with. Any suggestions welcome!
