Abstract: A system includes an RF signaling device configured to record a count of a number of times that an aircraft door or cover has opened or closed, and a management device configured to determine a state of the aircraft door or cover based on communication with the RF signaling device.

Abstract: Systems and methods are disclosed to adapt RFID tags in a master-slave configuration and to connect them by a connector. Upon a request from a reader, the slave RFID tag will transmit via the connector data to the master RFID tag which will concatenate the latter with its own data and transmit a concatenated series of data to the reader. Such RFID tags are presented in use in a system for managing a plurality of equipment stored in a plurality of housings, as is the case for a room of IT servers. Each such slave RFID tag is fastened preferably onto a housing, contains information on the housing, and is connected to the master RFID tag preferably fastened onto the equipment stored in the housing and containing information on the equipment. A user thereby knows in a single reading information about the equipment and the housing that it occupies.
