Abstract
An IC card incorporates a processor, a memory, etc. The memory stores therein a general electronic money balance having an unlimited use range, a specific electronic money balance having a limited use range, and available genre information defining a use range of the specific electronic money balance. A transfer processing unit serves to transfer a specified amount of money from the general electronic money balance to the specific electronic money balance between two IC cards. A settlement processing unit compares genre information acquired from a purchased commodity or a provided service with the available genre information of the IC card and, only when a coincidence has occurred, deducts the purchased amount of money from the specific electronic money balance of the IC card.
