If you run a website on finance or something related to it where you have discussions on different currencies then you would need a currency converter directly on your website which can help your visitors check the current rate directly without the need to visit any other online Currency Exchange Converters.
Check out WidgetBox for currency converter which offers you with a very small amount of javascript code to be added anywhere on any platform of websites and you get a working converter live. You can even customize the complete widget before adding on your website by making background changes.
Code to Add on your blog/website :
<script type="text/javascript" src="http://cdn.widgetserver.com/syndication/subscriber/InsertWidget.js"></script><script>if (WIDGETBOX) WIDGETBOX.renderWidget('d6ab2030-c741-437f-be67-b9e16011af4a');</script>
