Abstract: A system and method are provided for authentication. A first request for a transaction is received from a communications device, the first request comprising collation information of a customer to be authenticated and a price of a product or service to be purchased by the customer. An authentication level is set based on the price. A second request is transmitted to a mobile communications device of the customer. Authentication information is received from the mobile communications device, the authentication information comprising identification information of the customer. The authentication information is transmitted to the communications device.

Abstract: The object of the present invention is to provide an authentication system capable of achieving suitable authentication processing while guaranteeing the maximum convenience for the customer. A first communication terminal PD1 is built into a television TV that can be connected to the Internet, and communications with an authentication control company BS are possible via the first communication terminal PD1. The authentication control company BS is, for example, a telecommunications company, and performs authentication control for a plurality of product supplier companies SP1 to SP3 according to the product purchase status on the television TV. Furthermore, the present invention simplifies the appropriate procedures by setting authentication levels for authentication control.

Abstract: A money receiving system receives monetary payments without using cash or placing restrictions on recipients of such payments. This system uses an authentication management apparatus and a store communication terminal. The authentication management apparatus includes a receiver for receiving customer ID information, store ID information, and monetary amount information from a store communication terminal, an authentication device for authenticating the customer ID and the store ID, and a transfer device for transferring money indicated by the monetary amount from an account of a store to an account of a customer. The store communication terminal includes a memory for storing store information, a receiver for receiving customer information, an input device for inputting a monetary amount that a store is to pay a customer, and a transmitter for transmitting the store ID, the customer ID, and the monetary amount to an authentication management apparatus.

Abstract: For transmitting transmission data generated by a transmission data generator of a communication terminal device, a packet unit determining unit [17] determines a packet unit for a lowest data communication rate for the transmission of the transmission data, among packet units (packet sizes) that can be recognized by a destination communication terminal device and that can be transmitted from the communication terminal device. A packet generator [18] packetizes the transmission data according to the packet unit determined by the packet unit determining unit [17], and transmits the packetized transmission data to the destination communication terminal device.

Abstract: A slave communication device in a wireless LAN system uses a single wireless channel. When a telephone apparatus outside the network originates a call to the LAN, the originated call first terminates at a master communication device. A wireless telephone communication can then be established between that telephone apparatus and the slave communication device without relaying through the master communication device, and without requiring particular processing, such as authentication on a host station side. A first state is when a transmission/reception device of the master communication device is turned on and transmission/reception devices of slave communication devices are turned off. A second state is when the transmission/reception device of the master communication device is turned off and only the transmission/reception device of one of the slave communication devices which is a subject of control delegation is turned on.

Abstract: A wireless LAN system uses a single wireless telephone line. When a telephone apparatus outside the network originates a call to the LAN, the system allows establishment of wireless telephone communication between that telephone apparatus and a slave communication device. Each transmission/reception device is controlled to switch between a first state in normal times in which a transmission/reception device of a master communication device is turned on and transmission/reception device of respective slave communication devices are turned off and a second state in which the transmission/reception device of the master communication device is turned off and only the transmission/reception device of any one of the slave communication devices is turned on.
