PROBLEM TO BE SOLVED: To provide portable electronic equipment capable of efficiently grasping the situation of an access from the outside part and its history data storing method. SOLUTION: At the time of receiving instruction data, a CPU 21 of an IC card 1 confirms whether or not the instruction data are a command registered in a command control table 30 (ST14). In the case of the registered command, the CPU 21 judges whether or not log data should be stored (ST16), and which information (all data or the command or only a status code) should be recorded (ST19) (ST23) when the log data should be stored by referring to corresponding identification information. Then, information judged in the ST19 and ST23 is stored in the log data, and command processing is performed based on the received instruction data (ST22), and response data are outputted to an external device (reader/writer 4 or the like) (ST18). |
