1. A verification system for verifying turbojet engine parts in a turbojet engine accommodated in a nacelle compartment delimited by a nacelle wall and including at least one part equipped with an RFID tag, the verification system comprising:
an inner antenna accommodated in the nacelle compartment, the inner antenna being arranged to allow the exchange of radiofrequency signals with the RFID tag,
an interface device including an access point located outside the nacelle compartment, the interface device being arranged to be able to be connected to an interrogator device arranged to communicate with the RFID tag, and
a transmission line connecting the interface device to the inner antenna so that an interrogator signal from the interrogator device that is processed by the interface device is re-emitted by the inner antenna to the RFID tag, and a response signal sent by the RFID tag receiving the interrogator signal is received by the inner antenna and re-emitted by the interface device to the interrogator device.
