I found that the chart api works fine with a relatively simple url but when you try to feed it something like:
...com/showcaseproductdetail.htm?ID=157729&Used=1&
it will not encode the whole address resulting in the wrong qr code. Rather than attempt to convert the longer url’s to UTF-8, which presents a risk of not being read properly, I was wondering if you had a relatively simple solution to use the google url shortener within the script (preferrably not the .qr option in the shortener as it defaults to a size too small for print).

<5cript type="text/javascript">
document.write( '<1mg src=\"http://chart.apis.google.com/chart?chs=220x220&cht=qr&chl=' + location.href + '\">' );

how to make the background of qrcode transparent? I am not talking about the margin space around qrcode. I succeeded changing background of the margin space. But I want to make the background of the actual code transparent, too.

@Dean, you may have an issue in how you escaped the URL. This seems to work:

Looks like Google has canned this product?

This url used to work now it doesn't - what gives google?

Actually, my previous post was missing the final 'void 0':

javascript:u=window.location.href;sz=20*Math.ceil(Math.sqrt(u.length));szp=sz+'x'+sz;window.open('http://chart.apis.google.com/chart?cht=qr&chs='+szp+'&chl='+escape(u));void%200

Here's a bookmarklet to generate a QR code for the page you're currently viewing:

javascript:u=window.location.href;sz=20*Math.ceil(Math.sqrt(u.length));szp=sz+'x'+sz;window.open('http://chart.apis.google.com/chart?cht=qr&chs='+szp+'&chl='+escape(u));

If you want to decode 2D Codes (and also 1D Barcodes) with a simple API you should check out the Snappr.net API. Still in beta but works pretty nicely.

You certainly miss to specify the chart size in the URL(I did the same during two minutes...).

To use chart API, you must provide AT LEAST the following parameters:
Chart size (chs)
Chart type (cht)
Chart data (...)

Here is a working example :
http://chart.apis.google.com/chart?chs=150x150&cht=qr&chl=YouRules&choe=ISO-8859-1

I can't seem to get the QR code to work. No matter what info I put in the URL the QR code says:

"Bad Request

Your client has issued a malformed or illegal request."

All other charts work correctly. Any thoughts?
