Abstract
A telephone card has a part for storing the cumulative number of charged calls and a part for storing commercial information to be presented through a telephone set. The commercial information may be voice data to be played through a handset or speaker of the telephone set, and/or character or image data to be displayed on a display of the telephone set. When a card is inserted, the telephone set determines whether or not commercial information is present on the card. When commercial information is present, it is output before normal dialing can occur. When no commercial information is on the card, the telephone set is immediately connected for normal dialing.
