An airway pressure support system (2) that includes a pressure generating device (4) structured to produce a flow of gas and a component (8) such as a patient interface device (8) structured to be selectively coupled to the pressure generating device (4), wherein the pressure generating device (4) and the component (8) are structured to enable the component (8) to be to wirelessly identified by the pressure generating device (4) only when the component (8) is coupled to the pressure generating device (4). Also, a method of identifying a component (8) in an airway pressure support system (2) that includes steps of coupling the component (8) to a pressure generating device (4) of the airway pressure support system (2) and enabling the component (8) to be to wirelessly identified by the pressure generating device (4) only when the component (8) is coupled to the pressure generating device.
