Barcode field not working on mobile devices

Hi

I have a barcode reading field on my form. I placed the form in a iframe in another another page:-

http://www.dreamsitedesign.co.uk/Track%20A%20Tool/

The barcode field works on a desktop but not on mobile devices (which is what I really want).

However if I look at the form on the Jotform server it works on all devices.

Any ideas?

Thanks in advance
