Carlos,
They do have one for the CAC. Those are the ones I said they were handing out at the Air Force ID card office the other day. I just got a new contractor CAC, as well as a new retired ID (lamination was separating on my old one), and they gave me two of the foil lined holders. I also saw on that website Mike posted that there is a see-through holder that has a picture of a CAC in it. I'm going to look into that one as well.
All the best,
Glenn
