title: barcode scanner in JavaScript? Or plugin/extension
body: <p>I'm looking at writing a USB barcode scanner interface to a web application (offline app).  By this I mean that the scanner will be on the client machine not server.  So I was wondering what the best design would be.</p>
  
  <p>I know I could write an ActiveX object or native plugin into some browser but this is not ideal, does anyone know if chrome extensions (in javascript) or firefox jetpack would support this kind of functionality.</p>
  
  <p>Any ideas? I would appreciate any leads to follow.</p>
  
  <p>Thanks All</p>
