Abstract: Prepaid card, used in public telephones, with an integrated circuit which is capable of preventing increasing the usable amount of money and in the process of minimising the capacity of its memory. The prepaid card with an integrated circuit is controlled in that an input-output stage of the card is compelled to receive a new usable amount of money and an instruction to communicate from a public telephone, in that it is determined whether the instruction to communicate which is received from the input-output stage is a command to update the usable amount of money stored in a memory of the card, in that a comparator, with which the card is equipped, is compelled to compare the new usable amount of money with the usable amount of money which is stored in the memory, and in that an updating of the usable amount of money which is stored in the memory is controlled on the basis of the result of the comparison.

Abstract: PURPOSE: To prevent the increase of the usable amount of the user of a prepaid card used for card type public telephone sets and, at the same time, to minimize the capacity of a memory which stores the usable amount. CONSTITUTION: A prepaid integrated circuit card is provided with a control section 20 which makes an input-output section 10 receive a new usable amount and instruction words for communication from a public telephone set 50 and discriminates whether or not an instruction word for communication received by means of the section 10 is the updating instruction of the usable amount stored in a memory 40. The control section 20 makes a comparator 30 compare the usable amount stored in the memory 40 with the new usable amount and controls the updating of the usable amount stored in the memory 40 based on the compared results.

Abstract: A coin/credit operated public telephone is capable of making local, toll, and international calls using coins, credit card, or IC card and also of making a voice announcement regarding its operation method to the caller through a handset (1). Moreover, it provides graphic/character information through the LCD (10) and can transmit fault status that has been detected as a result of a highly reliable self-diagnosis carried out by receiving control signals from a remotely located central management system.
