Abstract:
1. A method for an integrated circuit card, comprising: maintaining the integrated circuit card in a power-on state; detecting availability of a first communication mode using a first transfer interface; asserting a first communication mode signal indicative of the detected availability of the first communication mode; blocking detection of availability of a second communication mode in cooperation with the first communication mode signal; transmitting data from the integrated circuit card according to the first communication mode using the first transfer interface within the integrated circuit card; unblocking detection of availability of the second communication mode after communication according to the first mode has stabilized; detecting availability of the second communication mode using a second transfer interface after initiating the transmitting of data in the first communication mode while continuing to maintain the integrated circuit card in the power-on state; and transmitting data from the integrated circuit card according to the second communication mode using the second transfer interface within the integrated circuit card while continuing to maintain the integrated circuit card in the power-on state.
