Claim 7:
8. A method for operating a universal integrated circuit card (UICC) in a device, the method comprising:
receiving, by the UICC, a low-power mode indicator from a near field communication (NFC) controller of the device, the low-power mode indicator designating an operation of the device in a low-power operating mode;
retrieving a configuration indicator from an auxiliary memory of the UICC in response to receiving the low-power mode indicator, the UICC using the configuration indicator to switch a single wire protocol (SWP) link for operating the UICC in the low-power operating mode; and
communicating, by the UICC, in the low-power operating mode with the NFC controller, wherein the UICC is powered by the NFC controller in the low-power operating mode.
