Defense Enrollment Eligibility Reporting System (DEERS) is a computerized database for United States Service members, military retirees, 100% VA Disabled Veterans, dependents, DoD active Contractors, and others worldwide who are entitled to Public Key Infrastructure and TRICARE eligibility.
DEERS is used in the Real-Time Automated Personnel Identification System (RAPIDS). RAPIDS is United States Department of Defense system to issue the definitive credential within DoD for obtaining Common Access Card tokens in the DoD PKI. Used together, these two systems are referred to as a DEERS/RAPIDS stations, available in 700 locations in the world.
With the expansion of base exchange online shopping privileges to all honorably discharged veterans beginning in 2017,[1] the DEERS database is also used to verify non-disabled veterans' eligibility for the Veteran online shopping benefit.[2]
