When the first antenna of the upper body is inserted through a seal sleeve of the central sleeve of the lower body, a pawl suitably is placed at a middle of the first antenna gets stuck inside a pawl ring of the central sleeve of the lower body when passing through it and thus activates and completes the passive RFID-based electronic seal.
