<p>The user of a mobile communication terminal uses a valuta management application 31 to manage value information, and sets a threshold value to a valuta display control unit 32. Thereafter, when the user performs deduction of "valuta", the valuta display control unit 32 makes a decision as to whether or not the valuta balance is less than or equal to the threshold value. If this decision is affirmative, then a display device 13, along with performing a display to the effect that the valuta balance has become less than or equal to the threshold value, also performs a display urging the purchase of "valuta", and the user performs additional purchase of "valuta" according to this display. Accordingly, it is possible for the user to confirm that the "valuta" which is stored is within a predetermined range, so that the convenience is enhanced.</p> |
