Generally, one refers to service devices and access to service devices. Area access control can be viewed as being provided by a service device (e.g., an automated door or gate), access to which permits entry to (or exit from) a controlled area. Information about the surrounding environment includes, but is not limited to, the presence or absence of particular individuals, the presence or absence of other service devices, the location and/or proximity of other service devices, the location of the user requesting access to the service device, and so on. Based on knowledge of the surrounding environment, service access to the device can be permitted or denied.
