  • Patent number: 6208722
    Abstract: A method of accepting the charges for individual connections in a telephone network is proposed, where the called subscriber station signals the cost acceptance, in that an identification number stored on a chip card is read by a card reader 3 of the subscriber terminal 2, and/or is transmitted to the central unit 1 together with a cost acceptance signal. To carry out the method, the telephone network contains means for processing the transmitted binding cost acceptance signals and switch-off signals. The terminals must be able to transmit the corresponding signals.

  • Patent number: 6126069
    Abstract: Anonymous use of and payment for, as well as collection of statistics, fee-based services, in particular Near-VOD services, employing a single chip card that can be used for all service providers. The chip card is used for paying for fee-based services of different service providers. Storage of usage-related data for collection of statistics and for payment for fee-based services as well as an authorization check is provided on the chip card. When an amount of money is loaded onto the chip card, these data are read and transmitted to a central office for the purpose of collecting statistics relating to the usage of individual services and crediting the individual service providers while, at the same time, guaranteeing anonymity of the individual customer-specific data.
