Or should I rather say Taiwan as the characters do not look Mao style aka simplified?

Btw: Ogilvy Taiwan and Motorola did a survey on QR Codes in July and they used Chragi's illustration for it, naturally with our approval.

Duncan Sample has made a cool Firefox QR Code Add-on. I had trouble refinding it in May (see comments in Kelly Goto's post) and use it since then. Now more and more people ask me for it, which brings me to make this post.

One warning though: This extension translates your URL straight away into a QR Code which means that you have to be sure that the site URL you are rendering is good to use on a mobile phone. If you have a Kaywa Blog, do not use the web address for now (this will probably change in the future), but add the /mobile to it. As an example do not use http://mobile.kaywa.com, use http://mobile.kaywa.com/mobile to generate the QR Code instead.

From the Mobile Barcoder site:

This extension generates 2D barcodes (called QR Codes) of the URL of the current page being viewed. You can then use a mobile phone to read the URL from the screen to save you typing the long URL using the phone keypad. Many Japanese phones already have this capability, Nokia S60 phones are beginning to get some/better applications.

Works with: Firefox 1.0 - 2.0.0.* ALL

* By the way, you can also create your QR Code by going to http://qrcode.kaywa.com where you can also generate SMS, Text, Phone Numbers. And if you don't have a mobile version, there's always Feed2Mobile.
