PROBLEM TO BE SOLVED: To improve the availability of a processing result history storing memory if an information processor. SOLUTION: A processing result in each end of execution of each processing in a set of processing to be applied to a processing target 2 such as an IC card is stored in a volatile memory 5b, and after the normal end of all the processing of the set, information indicating only the normal end is stored in a non-voltile memory 6b as history information. When abnormal end occurs during the execution of the processing set, both of information indicating the abnormal end of the processing set and the processing result recorded in the memory 5b are stored in the memory 6b as history information. |
