qr code generator

Because my QR generator needs to do this on a list from a DB it could generate up to 30 or 40 codes per page. So I need it to be fast.
I've been using this but it takes a few milliseconds per QR code.
Anyone have something faster than this routine.

html "<script src='http://ajax.googleapis.com/ajax/libs/jquery/1.11.2/jquery.min.js'></script>
<script type='text/javascript'>
function generateBarCode()
{
var nric = $('#text').val();
var url = 'https://api.qrserver.com/v1/create-qr-code/?data=' + nric + '&size=50x50';
$('#barcode').attr('src', url);
}
</script>"

html "<input id='text' type='text' value='Test QR Code' style='Width:20%' onblur='generateBarCode();' />"

html "<img id='barcode'
src='https://api.qrserver.com/v1/create-qr-code/?data=HelloWorld&size=100x100'
alt=''
title='1234567890'
width='200'
height='200' />"
wait

Thanks for the help..
