ABSTRACT:
An integrated circuit card includes an interface block for performing an interface function with the external devices and a power controller for controlling power of a security integrated circuit for detecting if an operational environment is in an abnormal state, the power controller periodically and selectively applies power to the security integrated circuit. Thus, power consumption is reduced in the integrated circuit card; and a stable operation of the integrated circuit card which contactlessly communicates with the external devices can be secured with an extended communication distance.
