FAQs About Card Acquiring Service
More than 60 federal agencies use CAS, including the Department of Commerce, Department of State, the Department of Veterans Affairs, The U.S. Forest Service, and the National Park Service.
Most federal agencies that accept credit or debit cards for payment MUST use CAS. Only groups with authority to process credit and debit cards on their own do not participate in CAS, including the U.S. Postal Service, Army/Air Force Exchange Service, Navy Exchange, and the Smithsonian.
