Publication number: 20060145817Abstract: A hierarchical structure is established among a plurality of RFID tags, such that ID numbers can be read only from RFID tags which belong to a particular layer. RFID tag can control whether permission should be given to read its ID number therefrom to protect the ID number. Data held in the RFID tag can be read from the outside. RFID tag comprises a memory circuit having a function of holding data, and a logic circuit having a function of processing a control command received from outside. Memory circuit stores an own ID nmber for identifying the RFID tag itself, and a parent ID number for identifying a second RFID tag. When RFID tag receives an ID number read command which contains first data as a parameter from outside, the logic circuit outputs the own ID number to outside only when the first data matches the parent ID number.Type: ApplicationFiled: December 28, 2005Publication date: July 6, 2006Inventors: Makoto Aikawa, Yutaka Takami, Shinichiro Fukushima, Masumi Moritani, Hashimoto Kazunori

Electronic money transaction system with a radio transmitter and receiver using a portable telephone
Patent number: 6902106Abstract: A terminal 2 held by the user is provided with a radio transmitter and receiver 3. Electronic money information is transferred via the radio transmitter and receiver 3. By using a portable telephone, it is unnecessary to directly insert an IC card 1 into service supply equipment 17. In addition to the service supply equipment 17, a device 9 for storing electronic money information in a lump is provided. Since the electronic money information is transferred into the device 9 for storing the electronic money information in a lump, it is unnecessary to collect the electronic money information stored in terminals one by one.Type: GrantFiled: December 11, 2002Date of Patent: June 7, 2005Assignee: Hitachi, Ltd.Inventors: Yutaka Takami, Kenji Matsumoto, Shigeyuki Itoh -
Publication number: 20050098628Abstract: In a settlement transaction system or settlement transaction method using the system, the system includes a content providing server conducting a digital broadcast, for example, for a CS broadcast, a BS broadcast, a CATV, or a broadcast using ground waves; a settlement server to execute settlement transaction or settlement transaction, an order placement managing server to execute order placement processing, and an order managing server which receives an order of a request from a user to purchase articles and which sends an associated indication to the settlement server and the order placement managing server according to information of the order. The user operates a terminal in which an IC card communication application to communicate with an IC card is only installed. It then becomes possible to reduce a load imposed onto the system in association with a change to an existing digital broadcast system.Type: ApplicationFiled: April 28, 2004Publication date: May 12, 2005Inventors: Kazunori Hashimoto, Yutaka Takami, Makoto Aikawa

Patent number: 6840448Abstract: When an IC card module is used for a small portable information apparatus such as a portable telephone terminal, the module has a size much smaller than an ordinary IC card from the viewpoint that the apparatus is required to be small in size and weight. In the case of a small non-contact type card, there are problems that an antenna coil cannot secure its necessary surface area, a necessary power cannot be obtained for a signal to be transmitted or received, a communication distance from an external device becomes small. When the signal is transmitted and received via a booster coil provided between the external device and the antenna coil of the IC card module, the effective surface area of the antenna coil can be increased and the communication distance can be increased to a level as large as it can practically avoid involvement of any problem.Type: GrantFiled: June 17, 2003Date of Patent: January 11, 2005Assignees: Hitachi, Ltd., Hitachi Maxell, Ltd.Inventors: Shinichiro Fukushima, Yutaka Takami, Atsushi Yoshioka, Isao Nakagawa, Shuzo Matsumoto, Kiyoharu Kishimoto

Publication number: 20040256470Abstract: Information recorded by an application provider in an IC card can be referred to, read out or changed by another application provider. The IC card has a plurality of cipher keys for reading out or writing the information recorded in the IC card, and provides a cipher key conversion function for encryption with a file capable of being managed, read out or written by the application provider himself using the cipher key. By the cipher key conversion function, data can be read out or written from or in the file of the other application provider.Type: ApplicationFiled: April 29, 2004Publication date: December 23, 2004Inventors: Yutaka Takami, Shinichiro Fukushima, Kazunori Hashimoto, Makoto Aikawa, Tetsuharu Inamitsu

Publication number: 20040256455Abstract: In a portable terminal having an IC card, the outstanding SF value, the commuter pass information and the conditions for the corresponding operation to charge the SF value or renew the validity period of the commuter pass are stored in the IC card. The outstanding SF value and the validity period of the commuter pass are checked at a predetermined timing. In the case where the outstanding SF value and the validity period satisfy the conditions for the corresponding operation (in the case where the outstanding SF value is reduced to less than a predetermined amount, for example), the set corresponding operation is performed. Thus, a predetermined amount is charged against the outstanding SF value, or the oncoming expiry of the validity period of the commuter pass is notified. The conditions for the corresponding operation can be set and changed appropriately at the portable terminal.Type: ApplicationFiled: March 30, 2004Publication date: December 23, 2004Inventors: Shinichiro Fukushima, Kazunori Hashimoto, Makoto Aikawa, Hidenori Nanami, Yutaka Takami
