RFID system configured for being installed on-board a first guided vehicle in order to allow the latter to automatically exchange information with a second guided vehicle, the RFID system according to the invention comprising: - an RFID reader configured for being installed in a location on the first guided vehicle that allows said RFID reader to read an RFID tag of an RFID system installed on-board the second guided vehicle when the first guided vehicle and the second guided vehicle cross each other; - an RFID tag configured for being installed in a location on the first guided vehicle that allows said RFID tag to be read by an RFID reader of the RFID system installed on-board the second guided vehicle when the first guided vehicle and the second guided vehicle cross each other; - an Information Collector Module, hereafter called "ICM", wherein said ICM is configured for being connected to an on-board device (2, 3) of the first guided vehicle for acquiring/transmitting data from/to said on-board device (2, 3), said ICM being connected to the RFID reader for getting additional data (Da) wherein the additional data (Da) are data acquired by the RFID reader when reading the RFID tag of the RFID system equipping the second guided vehicle, said ICM being furthermore connected to the RFID tag for providing the latter with selected data (Ds) that are data selected from the data acquired from the on-board device (2,3) and designed for being read by the RFID reader of the RFID system of the second guided vehicle, wherein the selected data (Ds) are configured for triggering a reconfiguration of the RFID tag of the RFID system equipping the second vehicle by means of an ICM of the latter, so that its RFID tag transmits at least part of the selected data to each next guided vehicle it crosses. - an RFID reader configured for being installed in a location on the first guided vehicle that allows said RFID reader to read an RFID tag of an RFID system installed on-board the second guided vehicle when the first guided vehicle and the second guided vehicle cross each other; - an RFID tag configured for being installed in a location on the first guided vehicle that allows said RFID tag to be read by an RFID reader of the RFID system installed on-board the second guided vehicle when the first guided vehicle and the second guided vehicle cross each other; - an Information Collector Module, hereafter called "ICM", wherein said ICM is configured for being connected to an on-board device (2, 3) of the first guided vehicle for acquiring/transmitting data from/to said on-board device (2, 3), said ICM being connected to the RFID reader for getting additional data (Da) wherein the additional data (Da) are data acquired by the RFID reader when reading the RFID tag of the RFID system equipping the second guided vehicle, said ICM being furthermore connected to the RFID tag for providing the latter with selected data (Ds) that are data selected from the data acquired from the on-board device (2,3) and designed for being read by the RFID reader of the RFID system of the second guided vehicle, wherein the selected data (Ds) are configured for triggering a reconfiguration of the RFID tag of the RFID system equipping the second vehicle by means of an ICM of the latter, so that its RFID tag transmits at least part of the selected data to each next guided vehicle it crosses.
