Abstract
A method and apparatus for controlling access from a first area to a second area includes receiving an identity signal from an identifier input device, and checking for stored data indicating that the identity represented by the identity signal is registered as present in the first area. If a predetermined access requirement is fulfilled, then a pass signal at the first access controller is generated. To control access from the second area to a third area, an enter message is sent to a second controller with at least the identity and data indicating that the identity is present in an access area of the second controller. An exit message is sent to a third controller controlling access to the first area, including at least the identity and data indicating that the identity is not present in an access area of the third controller.
