ABSTRACT:
A credit only paystation for allowing a user to place telephone calls therefrom without having to use coinage coins. The paystation includes a reader to read the users credit information which may be encoded on the magnetic stripe of a conventional credit card. The paystation uses a microcomputer to process the credit information and the dialing information entered by the user. The paystation also allows the user to dial a plurality of nonrestricted numbers without having to use a credit card. The paystation is powered solely from the central office to which it is connected and keeps the transmitter turned off until it is needed.
