Abstract: A method of processing a transaction involving at least two parties includes establishing rules that define transaction processing between combinations of a plurality of origination entities and a plurality of destination entities and storing the rules at a storage arrangement associated with a host computer system. The method also includes receiving at the host computer system transaction information relating to the transaction between the two parties. One of the parties is a particular one of the origination entities and one of the parties is a particular one of the destination entities. The transaction information contains at least an identifier from which at least one of the parties may be identified. The method also includes using the transaction information at the host computer system to identify at least one of the parties and consulting the storage arrangement to determine the rules that define transaction processing for the at least one party.
