Abstract: An audiovisual terminal, an audiovisual authentication system, a method of authenticating audiovisual education, a remote education method, and a recording medium readable with the audiovisual terminal, all suitable for authenticating the actual viewing of education programs, especially to authenticate the actual viewing in remote education. Through the audiovisual terminal, a viewer of an audiovisual program enters a confirmation code which is specific to the audiovisual program and is transmitted to a principal who authenticates viewing of the program, and time information corresponding to the viewing confirmation code. The time information corresponding to the viewing confirmation code is typically a time point at which the code is entered. It may also be a time interval calculated, for example, from the entering time. The audiovisual terminal confirms whether the viewer is actually viewing a remote education program.

Abstract: An electronic money issuing system of low risk. A float center server (200) manages information on electronic money issued to a user and information on the capital (e.g. bank deposit and real estate) of the user and on credit limit backing the issuance of electronic money. Electronic money is issued for payment.

Abstract: The present invention provides an optical parallel transmission system which can achieve reduction of the processing time without adding many processing functions. A pattern data adder adds, to transmission data, pattern data determined from the transmission data so that the transmission data per one bit becomes data having a form close to a repetition of “1”, “0”, and optical parallel transmission by AC coupling is realized thereby.

Abstract: A photographing terminal device, an image processing server, a photographing method, and an image processing method are provided that make it possible to take pictures practically in unlimited number of frames without depending on memory devices provided in cameras and to simultaneously record additional information at the time of photographing. The photographing terminal device comprises a photographing section 114 for taking images of an object and producing image data, a transmitter 110 for sending the produced image data to a remote server in real time, and an additional information producing devices 111, 115 for producing additional data related to additional information in addition to the produced image data, and is adapted to send the image data together with the additional data to the remote server.

Abstract: A transaction payment system including a central processing system. The central processing system has an account file including a file portion having stored therein data relating to the accounts of users and a file portion having stored therein data relating to the accounts of stores, and an outstanding transaction file for storing outstanding transaction data. The central processing system comprises a CPU for checking with the transaction data on the outstanding transaction file whether a predetermined period of indulgence has elapsed from the date of each transaction. The sum of transaction involving lapse of the indulgence period and included in the transaction data on the outstanding transaction file is withdrawn from the corresponding user account on the account file and stored in the corresponding store account thereon.

Abstract: An electronic cash register comprises a keyboard having a cashing key for dispensing cash from a drawer and numerical keys for entering cashing sums, and keys or a card reader for entering customer identifying symbols. The register has a memory including a cashing file for storing cashing sums in corresponding relation to the customer identifying symbols. When a cashing sum is entered and the cashing key is depressed, the cashing sum entered and the corresponding customer identifying symbol are stored in the cashing file.

Abstract: An electronic cash register comprising a keyboard having keys for cash registration, a card reader for reading the data recorded in a card, a communication control unit for communicating with a center provided with a customer file having stored therein information as to customers, a device for converting data relating to the credit standing of the customer and forwarded from the center to visible information, a memory for storing data as to cash registration and data as to credit inquiries, and a control unit for processing cash registration, controlling transmission of the data read from the card to the center to be made in response to a communicaiton starting instruction and controlling conversion of the data received from the center to visible information.
