shiftUI is a universal bitcoin qrcode generator supporting altcoins through the ShapeShift API
Click here for a working example
To generate a QRCode from a Bitcoin address that can dynamically accept Litecoin, Dogecoin, Dash and more, all you need to do is download shiftUI and include these 2 lines of code in your html:
<div id="shiftUI" data-address="<YOUR BTC ADDRESS>"></div>
<script type="text/javascript" src="js/shiftUI.js"></script>
and these 2 lines in <head>
<script src="js/qrcode.js"></script>
<link rel="stylesheet" href="css/styles.css" type="text/css" media="screen"/>
shiftUI currently relies on jQuery and bootstrap, so if you haven't already, also include in <head>:
<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.4/css/bootstrap.min.css">
<script src="https://code.jquery.com/jquery-2.1.3.min.js"></script>
Keep on shifting!
