The common access card, also commonly referred to as the CAC, is the standard identification for active duty United States defense personnel. The card itself is a smart card about the size of a credit card. Defense personnel that use the CAC include the Selected Reserve and National Guard, United States Department of Defense (DoD) civilian employees, United States Coast Guard (USCG) civilian employees and eligible DoD and USCG contractor personnel.
