An electronic money system has an IC card (10) for electronic money having a memory (101) for maintaining money deposit and money debit information and another memory (103), such as an EPROM, for storing transaction data, including detailed information of transactions, such as the content of a typical receipt received from a retail store. The transaction information can be used at a later time in a personal computer (32) so that an electronic record of household expenses can be maintained. The transaction data that is stored includes the product name, price of the product, quantity of the product purchased and similar details of the transaction. The IC card memory (103) can record the name and telephone number of a retail store where the card has been used or a network address can be recorded in the memory for use by a customer to access electronic direct mail information by using a PC. Also, a store can determine whether a particular purchase is within a range of average purchases in terms of the number of products being purchased in a transaction and the total cost of the transaction, based on the stored transaction information. <IMAGE> |
