Abstract

PURPOSE:To write and read telephone information on and from a magnetic card automatically by controlling a magnetic card reader-writer when the control circuit of a magnetic card telephone set receives an audio signal indicating a request or permit for duplication. CONSTITUTION:On magnetic card 1, telephone information regarding an owner and that on a party side are recorded. Magnetic card telephone set T is provided with magnetic card reader-writer 10, display 3 and microprocessor MPU8 controlling the entirety of the telephone set and MPU8, when receiving a duplication-request audio signal under a specified condition, controls reader-writer 10 by a program in memory 9 to read and send the contents of card 1 to a circuit. On receiving a duplication-permit audio signal, MPU8 brings reader-writer 10 under control to write telephone information sent next on the magnetic card. Consequently, when the party side makes a request, the telephone information can be read out from the card automatically and sent out or written on the card.
