Abstract (en)
[origin: EP2521072A1] The device (F2) has a connection unit (3) for electrically connecting an integrated circuit component (Sim) to a primary battery (B1) and/or an external source (T). A Near field communication (NFC)controller (2) selects an electromagnetic current power supply for the component. An alternative power supply source supplies power to the component during reception of an electromagnetic field as soon as the electromagnetic power supply current received by the component is insufficient. The alternative power supply source comprises a secondary battery (b3) and/or a capacitor. An independent claim is also included for a radio-frequency communication method.
