- a cellular telephone having a handset and a transceiver unit coupled together via a communications bus, said communications bus carrying audio transmission signals, audio receive signals, data transmission signals and data receive signals between said handset and said transceiver unit, said handset adapted to accept a destination telephone number from said user as part of initiating a telephonic communications link with a telephonic device corresponding to said destination telephone number;
a credit card interface unit coupled to said communications bus, said interface unit having means for selectively monitoring, blocking, modifying and passing said audio transmission signals, audio receive signals, data transmission signals and data receive signals between said handset and said transceiver unit;
a credit card data input device coupled to said interface unit;
as part of said interface unit;
means for blocking all said audio transmission signals, audio receive signals, data transmission signals and data receive signals except emergency signals until said user inputs his or her credit card data into said card data input device;
means for inserting a predetermined call placement telephone number into at least one of said audio transmission signals and data transmission signals along with said credit card data and said destination telephone data and for sending such data and signals to said telecommunications network via said transceiver and said communications bus;
said telecommunications network having;
a network transceiver associated with said call placement telephone number, said network transceiver receiving said credit card data and said destination telephone data from said cellular telephone transceiver and having means for ascertaining the validity of said credit card data with said credit card verification component before completion of said telephonic communications link between said cellular telephone and said telephonic device corresponding to said destination telephone number.

Abstract
The cellular telephone credit card calling system works in conjunction with a cellular telephone, a local cellular network and an IXC in a telecommunications network. The cellular telephone has a handset and a transceiver unit coupled together by a power and a communications bus. A credit card interface unit is coupled to the bus. The interface unit has a credit card reader and an electronic system which initially validates the credit card. The cellular telephone also includes electronic circuitry which establishes a first telephone communications link with the network and transmits, via the transceiver unit for the phone, to the network, credit card data, a cellular telephone ID data and the telephone number input into the handset by the user. Upon receipt of at least the credit card data, a network transceiver verifies the validity of the user'"'"'s credit card. After the credit card has been validated by the IXC through a verification or validation computer service, the network transceiver then completes a further telephonic communications link between the cellular telephone, operated by the user, and the telephonic device associated with the input telephone number, that is, the third party'"'"'s telephone. Since the network transceiver does not complete the call to the third party prior to validation of the user'"'"'s credit card, the system operates in real time. Further, in a preferred embodiment, the network transceiver provides some type of indication to the credit interface unit that the credit card has been validated. Thereafter, the user is permitted to make additional cellular telephone calls without requiring further validation of the credit card data by the network transceiver.
