Create QRcode with google chart API

Google recently add QRCode to its Chart API. This make QRCode generation a breeze. All you need to do is sending a GET request to google.
QR Code is the most popular 2d barcode. I put a page up that make it easy to generate QR Code with Google Chart API:

To create a URL, you need to put 'http://' at the beginning. Otherwise code reader will see it as just text. Likewise to create a telephone number, you need to put 'tel:' at the beginning, otherwise it's just code and you can't dial it from your phone.

There're a lot of code readers. I have Kaywa Reader on my cellphone, it works really well.

    Hey, man, what a great page to generate QR Codes you made.
    Congratulations!
    I have a question:
    - Would it be possible for me to have the gqrcode.js script you have in your site, so I can deploy this application on my site too?

    I would really appreciate that.
    Again: congratulations for the nice page.
