The communication module 13 detects, in a predetermined operation mode in which the main processor 11 stops operation, another portable communication terminal existing in a range in which a communication connection is possible, determines the detected portable communication terminal as a target terminal from which target data is obtained, obtains the target data transmitted from the determined target terminal, and stores identification information for identifying the target terminal into the internal memory 13b. The main processor 11 executes processing using the obtained target data. The communication module 13 determines, while the main processor remains stopped, whether or not the identification information of the detected portable communication terminal is already stored in the internal memory 13b, and, under a condition that the identification information is determined to be stored, does not determine the detected portable communication terminal as the target terminal.
