Abstract: When a certificate is to be printed on a certificate form having a microchip built therein, an applicant for applying for the certificate sends microchip ID to a certificate issuer, and the certificate issuer stores certificate data in association with the microchip ID in an issue management database of the certificate issuer. When the certificate is to be verified, a certificate verifier sends the microchip ID built in the certificate to the certificate issuer, and in response to it, the certificate issuer sends the certificate data, which is registered in the certificate database in association with the microchip ID, to the certificate verifier. Certificate can be printed out by a print terminal at home or the like.

Abstract: A multi-electronic money settlement-of-account vicarious execution system includes a store information storage section. The storage section includes a store information database for storing information of a store-specified money kind specified by the store as a kind of money to be received by the store and information of a store-specified money remittance destination specified by the store as a remittance destination of money. The system further includes an electronic money conversion and remittance section for converting electronic money received from a store user to money of the store-specified money kind in accordance with the information of the store-specified money kind, and remitting money resultant from the conversion to the store-specified money remittance destination in accordance with the information of the store-specified money remittance destination. The store information database stores information of point kinds to be provided for the user.

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: When conference conditions are set by a conference sponsor, a conference sponsor agent inquires of schedule management agents of requested attendants about available time within a range of set dates, determines an optimum conference schedule on the basis of the available time of the individual requested attendants, sends to the conference sponsor the conference schedule for confirmation thereof, and sends a conference notification to the requested attendants. In order to permit an input value set by a user to have a range in accordance with the kind of parameter requiring the input value and conditions at that time, an input value acquiring element acquires an input value of a parameter necessary for a processing realized by an application element, the input value being set by the user by an input element.

Abstract: A system for processing information with an electronic pen includes a coordinates indicating device and a coordinates sensing device. Both of the devices serves to output the information stored in itself to each other and store the information outputted from the other. The power supply for driving the information processing system itself is fed by a battery built in the coordinates indicating device.
