Abstract: An interface system for providing access to a plurality of payment networks is provided that displays to a user a single transaction entry screen capable of initiating a monetary payment transaction over any of a number of differing payment networks. The interface is coupled to a display of a remote computer operated by the user. A plurality of such remote computers are coupled to a central computer, which transfers payment requests initiated by the user to the various selected payment networks. Selection logic is provided at the remote computers to allow the operator to select the particular payment network desired for each particular transaction. Upon selection of the desired payment initiation routine, the interface dynamically prompts the user only for data applicable and necessary to complete the particular transaction.
