1. A dynamic and recursive transaction gateway system, which is used as a common interface between originating systems that initiate transactions and end-point systems that are destinations of said transactions, comprising: a plurality of on ramps, a plurality of interchanges, and a plurality of off ramps; each of said on ramps comprising a firewall for data cleansing and validation, a dispatcher for managing transaction data processing, an event handler library comprising a plurality of handlers; said dispatcher comprising a first dispatcher program for converting original data formats used by said originating systems to a common data format used by said dynamic and recursive transaction gateway system, a second dispatcher program for first analyzing transaction data and originating system data and for then making processing decisions based on rule settings, a third dispatcher program for calling at least one of said handlers, a fourth dispatcher program for passing objects by reference to said interchanges, a fifth dispatcher program for monitoring status of said transactions and sub-transactions generated therefrom, and a sixth dispatcher program for converting said common data format to said original data formats; said handlers operable to perform a plurality of functions which include sending said transaction data to downstream processes of said dynamic and recursive transaction gateway system, halting said transaction data processing, managing validation response data from said interchanges to said originating systems, and managing end-point response data from said end-point systems to said originating systems; said handlers comprising a recursion handler operable to generate said sub-transactions from one of said transactions and feed said sub-transactions recursively to said dynamic and recursive transaction gateway system; said handlers comprising a tokenization handler operable to forward requests for tokenized data by said originating systems to said interchanges and manage sending said tokenized data to said originating systems; each of said interchanges comprising a first interchange program for inspecting credentials of said originating systems, a second interchange program for generating said tokenized data for said originating systems to replace sensitive data, a third interchange program for retrieving said tokenized data in said transactions, a fourth interchange program for decrypting encrypted data in said transactions, a fifth interchange program for making routing decisions, a sixth interchange program for conducting extended field validation of said transaction data, and a unified logging layer which ensures said transaction data to be logged in a consistent manner; and each of said off ramps comprising a protocol translator for translating between said common data format and end-point data formats used by said end-point systems and a dynamically loaded one of configurations, said dynamically loaded one specifically for at least one of said end-point systems, said configurations comprising interoperability constraints and end-point system data of said end-point systems and being in said dynamic and cursive transaction gateway system; wherein said originating system data includes originating system configurations and parameters of said originating systems and devices thereof; wherein said tokenized data includes first type tokens for predetermined numbers of said transactions, second type tokens for predetermined periods of time, third type tokens for unlimited time, and chain-bound tokens shared across locations; wherein respective ones of said sub-transactions are processed by respective ones of said on ramps, respective ones of said interchanges, and respective ones of said off ramps; and wherein said validation response data or said end-point response data with respect to said respective ones of said sub-transactions is bound to a universal transaction identification number which has been used by said one of said transactions, and sent to a specific one of said originating systems that has initiated said one of said transactions.
