摘要： The invention relates to a device for supplying energy to an RFID component, comprising an antenna and an energy store. The energy store stores energy that is induced into the antenna by an alternating electromagnetic field during a first time interval. Furthermore, the energy store supplies the RFID component with energy to maintain the functionality of the RFID component during a later second time interval if an energy induced by an alternating electromagnetic field during the later second time interval is not sufficient to supply the RFID component.
