SOLUTION: An ID is given to an electronic currency having a form of money or a card, and in addition to the ID, parity information for ID confirmation and an amount of money are written in the built-in IC, and reading / writing of data to the built-in IC is performed. Writing is performed by electrically contact means or non-contact means using electromagnetic waves or magnetism. The electronic currency is used while being connected to an electronic currency server via a network. This electronic currency secures the user's anonymity and the circulation.
