A data processing system coupled to a rules database and a customer database is responsive to transaction requests representative of money transfers. The rules database includes information representative of transaction rules such as location-based rules, transaction type-based rules, customer-based rules, aggregated transaction value rules and currency exchange rules, at least some of which include an aggregation threshold. The system processes the transaction requests during transaction processing sessions to enable enforcement of governmental money transfer compliance requirements. Responses including requests for additional information, approvals and denials are provided by the system.
