A nice simple way of generating QR codes using HTML and the Google Chart API.
<form method="get" action='https://chart.googleapis.com/chart'>
<input type="text" name="chs" value="150x150" />
<input type="text" name="cht" value="qr" />
<input type="text" name="chl" value="https://technologyisnotdull.blogspot.com" />
<input type="text" name="choe" value="UTF-8" />
<input type="submit" />
</form>
