A disc pump system comprising: a pump body having a substantially cylindrical shape defining a cavity for containing a fluid, the cavity being formed by a side wall closed at both ends by substantially circular end walls (20, 22), at least one of the end walls being a driven end wall having a central portion and a peripheral portion extending radially outwardly from the central portion of the driven end wall; an actuator operatively associated with the central portion of the driven end wall to cause an oscillatory motion of the driven end wall thereby generating displacement oscillations of the driven end wall in a direction substantially perpendicular thereto; an isolator positioned between the peripheral portion of the driven end wall and the side wall to reduce dampening of the displacement oscillations, the isolator comprising a flexible material that stretches and contracts in response to the oscillatory motion of the driven end wall; a first aperture in either one of the end walls and extending through the pump body; a second aperture in the pump body and extending through the pump body; and, a valve (29, 32) disposed in at least one of the first aperture and second aperture; characterised in that the disc pump system further comprises an RFID tag operatively associated with the flexible material of the isolator to store and transmit identification data associated with the isolator; and a sensor operable to measure performance data of the disc pump system and communicate the performance data to the RFID tag; wherein the RFID tag is operable to transmit the performance data to an RFID reader. a pump body having a substantially cylindrical shape defining a cavity for containing a fluid, the cavity being formed by a side wall closed at both ends by substantially circular end walls (20, 22), at least one of the end walls being a driven end wall having a central portion and a peripheral portion extending radially outwardly from the central portion of the driven end wall; an actuator operatively associated with the central portion of the driven end wall to cause an oscillatory motion of the driven end wall thereby generating displacement oscillations of the driven end wall in a direction substantially perpendicular thereto; an isolator positioned between the peripheral portion of the driven end wall and the side wall to reduce dampening of the displacement oscillations, the isolator comprising a flexible material that stretches and contracts in response to the oscillatory motion of the driven end wall; a first aperture in either one of the end walls and extending through the pump body; a second aperture in the pump body and extending through the pump body; and, a valve (29, 32) disposed in at least one of the first aperture and second aperture; characterised in that the disc pump system further comprises an RFID tag operatively associated with the flexible material of the isolator to store and transmit identification data associated with the isolator; and a sensor operable to measure performance data of the disc pump system and communicate the performance data to the RFID tag; wherein the RFID tag is operable to transmit the performance data to an RFID reader.
