An exemplary security system includes a credential holder having a credential database that contains specified secured area credential information indicating at least one secured access location between a specified secured area and a specified adjacent area where the credential information is valid for authorized access. An access control device at a selected position corresponding to the secured access location is configured to receive the credential information when the credential holder is near the access control device. A processor of the access control device has stored access control information including indications of the specified secured area, the specified adjacent area and the secured access location. The processor autonomously determines that access to the specified secured area will be granted when the received credential information corresponds to the stored indications. |
