摘要:
A portable terminal has a currency information storage device for storing therein currency information representing a currency value amount as an electronic data. An information processing device uses operational processing information to thereby operationally process a monetary amount of the stored currency information. A request information transmission device transmits, to a server apparatus, request information for requesting the server apparatus to rewrite the electronic data so as to increase the stored currency value amount by credit using the operational processing information. An operational processing information receipt device receives the operational processing information transmitted by the server apparatus in response to the transmitted request information. An input device inputs the received operational processing information into the information processing device.

A mobile terminal device has an information processing unit that processes electronic money information and a storage unit that stores the electronic money information. A receiving unit receives from an electronic money server an electronic money identification (ID), a mobile terminal identification (ID) identifying the mobile terminal device, and a money information processing program for enabling the information processing unit to execute processing of the money information stored in the storage unit. An installation unit installs into the storage unit the money information processing program and the IDs received by the receiving unit. A sending unit sends to the electronic money server information necessary for enabling the electronic money server to provide electronic money service, the necessary information being sent to the electronic server before the receiving unit receives the money information processing and the IDs.
摘要:
It is an object to provide a mobile terminal device, such as a mobile phone using electronic-money service, in which information is easily managed upon installing a value processing function to the mobile terminal device. An IC chip for non-contact IC card is installed to a mobile phone 7 having an Internet access function. At the selling time of the mobile phone 7, an application program is not installed in the IC chip. A user purchases the mobile phone 7, thereafter, accesses an electronic-money server 2 from the mobile phone 7, and installs a value processing program to the IC chip. The electronic-money server 2 and the mobile phone 7 are cooperated and install the value processing function. In the installing processing, the mobile phone 7 receives secret information from the electronic-money server 2 for the purpose of ensuring the security, and installs the information to the IC chip.

An object of the present invention is to, in settlement by electronic money, reduce burden on an electronic money server and enhance convenience for users. The function of generating transaction numbers is transferred from the electronic money server to affiliated store servers, so that the transaction numbers are generated by the affiliated store servers. The transaction numbers are each associated with transaction information calculated in accordance with a calculation rule confidential to third parties, such that the electronic money server can detect the presence of alteration of the transaction information based on the transaction number. Furthermore, at the time of generating a transaction number, a seed, which is time-limited secret information confidential to third parties, is inputted to the calculation rule along with the transaction information and used for calculating the transaction number, whereby it is possible to further enhance the level of security.
摘要:
A portable telephone (7) comprises a telephone function part (10) having a voice communications function and an Internet connecting function, and an electronic money function part (12) configured to conduct VALUE storage and VALUE handling. The telephone function part (10) is capable of accessing to a service site of an electronic money server (2) via Internet (4). Request by a user from the telephone function part (10) to the service site of the electronic money server (2) for VALUE entering, causes the electronic money server (2) to transmit an entering command to the portable telephone (7) for causing the electronic money function part (12) to execute VALUE entering. The electronic money function part (12) inputs the entering command in the electronic money function part (12) thereby causing the electronic money function part (12) to conduct an entering procedure.

摘要:
An object is to properly perform failure recovery in an electronic money system where on-line terminals and off-line terminals coexist. For both an electronic money card and a center server, a flag selectable between two values, “transaction in progress” and “transaction completed”, is prepared. In the course of processing information between the electronic money card and the center server, the processing is caused to progress while setting their flags on (inverting them from “transaction completed” to “transaction in progress”), or setting them off (resetting them from “transaction in progress” to “transaction completed”) in a synchronized manner. If any failure occurs during the processing, the state of the flag at the time of occurrence of the failure is saved in both of them, and therefore based on these states, it is possible to specify the time at which the failure has occurred.
