Abstract
When a portable terminal receives a condition for an exchange object from a portable terminal, it selects electronic values as exchange objects, out of lists constituting the condition. An IC card deletes the electronic value and sends a message addressed to the portable terminal. An IC card deletes the electronic value in conjunction with fulfillment of a predetermined condition and thereafter sends a message addressed to the IC card. The IC card stores the electronic value in conjunction with fulfillment of a predetermined condition and sends a message addressed to the IC card. The IC card stores the electronic value.
