Abstract
An interactive transaction system is provided. A user interacts with the system by means of a telephone which delivers output signals from the user and receives input signals from the system. The telephone is interfaced to a communication network through a switching unit. An account is provided from which the amount of the transaction is debited. A transaction microprocessor is interfaced to receive the input signals from the telephone which identify the transaction, the amount of the transaction and the user's personal identification code. The transaction microprocessor then communicates with the account microprocessor to authorize and complete the transaction.
