Abstract: An electronic money transferring method that enables the payment of electronic money through an electronic money transferring system with reliability. An external information processor is operated to enter the product number of a desired product, and then a host apparatus sends information about electronic money information indicating an amount of money necessary for purchasing the product, etc. to a control unit. The data processing unit reads electronic money information indicating the amount of money from an IC card. The electronic money information is transferred to the host apparatus.

Abstract: A system is provided to manage points provided by plural manufacturers and plural stores using one card. To achieve this object, the point management system has a point system management apparatus that administers the whole point system, a reading and writing apparatus which reads and writes the data from/into an IC card, and an IC card which ha a memory having plurality of point record areas that store point data transmitted from the reading and writing apparatus and a point management application that controls access to the point record area of the memory.

Abstract: When installing a new system application in the terminal device which can read from and store in the IC card, the application is installed by communicating with a host machine through a connector for the IC card attached to the terminal device, without an exclusive interface mechanism for installing the application.

Abstract: Premium point services offered by different retailers require each user to possess a plurality of cards for dealing with different applications. An electronic pocketbook system made of a display device and an IC card is provided to store diverse kinds of application information such as amount information and point information into a single IC card. Portions of the application information to be displayed are stored in a predetermined format into a predetermined area inside the IC card. This allows the same program of the display device to display various kinds of application information successively using a common program, and without having to an application specific program.

Abstract: A processing apparatus for processing information contained in an IC card. When an application is newly registered in the IC card, registration of a corresponding service application program in the processing apparatus is required. Further, when applications stored in the IC card differ from those stored in the processing apparatus, a method of displaying names of the applications in a uniformized manner is required. For coping with these cases, an IC card read/write unit of the processing apparatus is made use of for registering service application programs in a memory incorporated in the processing apparatus, while the application names are registered in a memory area of the IC card in a common character code for allowing the names of the applications registered in the IC card to be displayed whenever occasion requires.

Abstract: In a vending machine selling products and services without human attendance, at a point of sale, a discounting service is provided to each purchaser according to the frequency-of-purchase record of respective purchasers. A microcomputer 2 collects electronic money corresponding to prices of products purchased from a product purchaser's IC card 8 inserted into an IC card reading apparatus 1 by each purchaser, and transfers it to a product seller's IC card. Further, on this occasion, the number of times of purchase corresponding to a personal ID stored in a product purchaser's IC card 8 is stored on the number of-times of purchase list of the memory unit 3, and a personal ID is registered on the personal ID list of a memory unit 3.

Abstract: An IC card system includes an IC card, an IC card read/write unit for reading/writing the IC card, a communication unit intervening for connection to a communication line network, a controller for controlling the IC card read/write unit and communication unit, and a server system connected to the communication line network. The IC card is written with at least specified access destination information for accessing the server system, the controller automatically accesses the server system through the communication unit in accordance with the access destination information in the IC card, and the server system offers information to an information offering destination determined automatically by information to be offered which is processed by the server system, an information offering destination already written in the IC card inserted in the IC card read/write unit or an information offering destination designated by a user after the insertion of the IC card.

Abstract: A method for preventing unauthorized copying of digital information such as digitized movies, music, literature, or other works, and reliably collecting to the digital information owner fees paid for using the copied digital information. When copying key data 156 enabling use of digital information 158, the key data is locked. To unlock the key data, the user accesses digital information seller 150 and pays the digital information usage fee.

Abstract: A machine data acquisition system connected to a machine, for acquiring data on an internal status of the machine, and for use with an IC card having storage. The machine data acquisition system comprises an IC card accepting device which accepts the IC card, a machine data acquisition device which acquires data on the internal status of the connected machine, and a card writer which writes data acquired by the machine data acquisition device into the storage in the IC card.
