I can confirmed that the smart card reader is underneath the sd reader, lan and modem port. I have a CF-30EAXXX before with htis Smart card reader. Its a federal issue unit used by military.
Yup, I use the card reader for military use. I think we grunts are pretty much the only audiance for this hardware, at least in the Toughbook crowd. At least I have never seen anyone else using it. It used to be optional (read easier) to access government resource sites from home but now many of the sites are requiring the CAC card for security to even allow login.
If I had known that they moved it, I would have looked around a little longer to find a laptop that had the card reader already installed. Now the question becomes whether I can add it to my existing chassis or will I have to look for a donor federal model......
