php javascript java applet smart card signing pdf on server
<p>I am making a php app where I have generated pdf file on server which needs to be digitaly signed with smart card (using a smart card reader) by 2 to 60 people.</p>

<p>A simple button that says </p>

<blockquote>
  <p>Sign...</p>
</blockquote>

<p>Then if the user has no smart card in reader app to say:</p>

<blockquote>
  <p>Insert card,</p>
</blockquote>

<p>a new popup with:</p>

<blockquote>
  <p>input pin,</p>
</blockquote>

<p>and all ended with:</p>

<blockquote>
  <p>The document signed.</p>
</blockquote>

<p>Can it be done and how?</p>
