Zusammenfassung:A multi-interface integrated circuit (IC) card includes a first communication interface configured to communicate with a host device in a first protocol mode, a second communication interface configured to communicate with the host device in a second protocol mode different than the first protocol mode, and a controller configured to detect a voltage supplied by the host device and a counter value associated therewith. The controller is configured to enable either the first interface or the second interface according to the detected voltage and the counter value. Related methods of operation are also discussed.
