I am looking for APDU commands to be used for a DoD CAC. I'm trying to pull as much information as I can off the card. So far Google has not been of any help.
Try this link to get more information about the CAC card:
http://www.cac.mil/common-access-card/developer-resources/
In it you will find a standard document titled:
Interfaces for Personal Identity Verification – Part 2: End-Point PIV Card Application Card Command Interface
