Common Access Card (CAC) The CAC, a smart card about the size of a credit card, is the standard identification for active duty uniformed service personnel, Selected Reserve, DoD civilian employees, and eligible contractor personnel.
The Department of Defense Common Access Card is an everyday sight on military installations. From Soldiers to civilian employees, the card is a means of identification and access to various services on post â including access through the gates. Because the card is issued to Soldiers, civilian employees, affiliates, contractors, etc., each is distinguished by its own associated color. Within the next few months, CAC cards issued to new (or renewing) recipients will undergo a visual revamp in order to make each card distinction more noticeable.
