As access control system and method is provided. The access control system in one aspect may comprise a client application operable to provide a user interface for allowing a user to dynamically configure rules and associated parameters for controlling access to an entity; a rules engine proxy operable to receive said rules and associated parameters from the client application, the rules engine proxy further operable to dynamically compile and execute said rules; and a controller coupled to the rules engine proxy operable to receive input and further operable to trigger the rules engine proxy to execute one or more of said rules in response to the received input.

Access control system with rules engine architecture

A method for confirming entry and/or exit state of a mobile object relative to all entrance of an underground passageway by utilizing Radio Frequency Identification (RFID) technology. At least one RFID tag is physically attached to the mobile object. At least a first RFID reader and a second RFID reader, each having a monitoring range and being in communication with the RFID tag, are disposed at the entrance and a relatively inner position of the passageway respectively. The method comprises generating a first entering-state data if the RFID tag enters the monitoring range of the first RFID reader and a first exiting-state data if the RFID tag exits the monitoring range of the first RFID reader, generating a second entering-state data if the RFID tag enters the monitoring range of the second RFID reader and a second exiting-state data if the RFID tag exits the monitoring range of the second RFID reader, and processing the first entering-state and exiting-state data and the second entering-state and exiting-state data to generate an output data indicating the entry and/or exit state of the mobile object relative to the entrance of the passageway.
