Abstract
An apparatus for facilitating the making of a calling card telephone call includes a central processing unit (CPU) and a storage device for storing access data to enable access to a central telephone office connected to a telephone network, account data and a telephone number. The apparatus further includes a dialer capable of transmitting and receiving signals to and from the user interface, the telephone network and the central telephone office. The central processing unit, responsive to an entry of the telephone number on the user interface, stores the telephone number in the storage device. Thereafter, the CPU causes the dialer to transmit access data from the storage device, across the telephone network, to initiate communication with the central telephone office. Finally, the CPU, responsive to requests for information from the central telephone office, causes the dialer to transmit the telephone number and the account data in the order requested by the central telephone office, to complete the calling card transaction.
