Abstract
An automated calling card is provided having internal means for generating audible tones representative of a telephone number or calling card number to be dialed. A small, card-shaped unit houses a microprocessor or logic circuitry, including means for inputting data, memory, means for generating tones, a speaker and a display. Telephone numbers and information pertaining thereto can be stored into memory through use of a keypad on the card. A calling card number is also stored in memory. In use, audible tones representative of a telephone and/or calling card number desired to be dialed are generated by the card. Use of a Personal Identification Number prohibits unauthorized access to features of the card.
