A mobile terminal capable of determining whether a near field communication source is a mobile terminal or not, and capable of appropriately restricting information reading in near field communication. The mobile terminal includes an antenna for near field communication and an RF part. The RF part includes an electromotive force measuring part which measures the electromotive force of a carrier wave received by the antenna, a communication permission/prohibition determining part which, when the measured electromotive force is less than or equal to a predetermined threshold value, determines that the sender of the carrier wave is a mobile terminal and outputs a communication prohibition signal, and an RF controller which acquires the communication prohibition signal and locks the RF part.

Mobile terminal and information reading preventing method

A portable terminal supplies power to a chip card therein with host power off. A power controller supplies power from a battery to a host, the chip card, and a CLF; a first switch opens/closes a power supply channel to the chip card, branching from a power supply channel from the power controller to the host; a second switch opens/closes a power supply channel to the chip card, branching from a power supply channel from the power controller to the CLF; a switch controller opens the first switch and closes the second switch if the CLF detects a contactless RF signal, if the host is off or if the portable terminal is in a low battery mode, and if the contactless RF signal conforms to the communication method of the chip card, and the switch controller closes the first switch and opens the second switch if the host is on.

Portable terminal, recording medium

A secure element (SE) unitholding service data used by an application is provided in a UIM card. Thus, when the user identify module (UIM) cardis transferred between portable terminals, service data and accompanying information of the application can be moved together with the UIM cardto another portable terminal. In addition, an access management unitincluded in a portable terminalcompares UIM information of a UIM information storage unitwith UIM information, held by an authority information holding unit, of a UIM card of which use authority is possessed by an application. If they do not agree, access to service data stored in the SE unitis restricted.

Access management system and access management method

A reproducing apparatus () of the present invention receives information of a WEB site from a service-providing server () that administrates the WEB site, and reproduces the information. The service-providing server () holds identification information () of a user of a portable communication apparatus () that is permitted to access the WEB site. The reproducing apparatus () includes: a data receiving section for receiving, from the portable communication apparatus (), invitation information (), identification information (), and transmission time point information (); a reproducing apparatus infrared communication section; a destination determination section that establishes a connection to the service-providing server () based on the received invitation information (), and transmits the invitation information (), the identification information (), and transmission-instruction time (); and a reproducing apparatus communication control section. This allows the administrative server to confirm an authorized destination, based on the content request information received from the portable communication apparatus, when a content is provided from the administrative server managing the content.

Reproducing apparatus, portable communication apparatus, administrative server, and content distribution system

A mobile terminal capable of causing the user side to grasp whether or not a credit settlement service stops with a simple operation is provided. In the mobile terminal, validation and invalidation of a storage area within an IC chip assigned to an issuer application corresponding to one issuer are switched based on switching instruction information received from an issuer terminalmanaged by one issuer. Then, when the issuer application starts, there is displayed in a lump whether or not the respective issuer applications are available on a display part, based on state information indicating whether or not the respective storage areas are validated. Therefore, in the mobile terminal, even if plural issuer applications are stored, it is possible to cause the user side to grasp which kind of the credit settlement service stops, with a simple operation of only starting a management application.

Mobile terminal

An infrared communication apparatus and method enabling data communication with a receiving device, regardless of a protocol with which the receiving device is compatible. A transmitting unit transmits a first packet to inquire whether a receiving device is compatible with a first protocol and transmits a second packet to inquire whether the receiving device is compatible with a second protocol, to the receiving device at least once, and transmits a plurality of third packets to inquire whether the receiving device is compatible with a third protocol, to the receiving device. A receiving unit receives a response packet indicating a protocol with which the receiving device is compatible, from the receiving device having received the first packet, the second packet, and the plurality of third packets. A data transmitting unit transmits data to the receiving device, based on the protocol indicated by the response packet received by the receiving unit.
