Abstract
The invention relates to an integrated circuit card () comprising: an input/output block () for receiving external command data from an interface device (); a central processing unit (CPU) () in signal communication with the input/output block () for performing a task corresponding to the received command data; a judgement block () in signal communication with the central processing unit () for judging whether a working time of the central processing unit () reaches a reference time, after an input of the external command data is completed; and a control block () in signal communication with the judgement block () for operating responsive to an output of the judgement block, wherein the control block controls such that a S(WTX request) is output via the input/output block () without intervention by the central processing unit whenever the interface device () connected to the integrated circuit card () transmits a command to the integrated circuit card and the integrated circuit card is not able to respond to this command within the defined maximum waiting time.
