An intelligent electronic system for use with an item container/carrier, such as a suitcase, briefcase, backpack, car trunk, purse, wallet, storage compartment, storage facility, locker, or similar. The system is used with item containers/carriers that contain portable items which can be identified by electronic, optical, or similar means. For example, the portable items may be outfitted with portable item reporting devices (BIRDS) which provide item monitoring and signaling; or the portable items may be identified via RFID tags. The system includes a sensor to identify portable items in the container/carrier via their BIRD signals, RFID signatures, or optical signature. The system includes memory to store identifications of portable items. The system can store one or more lists of specified portable items which are expected to be present within the containers/carriers, possibly with different lists being applicable in different contexts. The system can scan the container to identify items which should be present, but are missing. The system can scan the container to establish a current list of present items, to be saved for future content assessments. The intelligent electronic system may be integrated into the structure of the container or carrier, making the container or carrier an intelligent container.
