A portable object (1) comprises a circuit (22) for receiving information conveyed by an energy field and an internal energy source (18). The portable object (1) further comprises: a switch (24), that connects the circuit (22) to the internal energy source (18) when the switch (24) receives a control energy that is above a threshold level; and a switch controller (23) that substantially derives the control energy from the energy field.
