A dynamic product tracking system uses RFID (radio frequency identification) to provide real time updates regarding item-level product movements, enriches the received RFID scan data with master and associative data, and stores the resulting enriched data in a product tracking server database. The product tracking server also stores static reference data, pre-defined rules or queries, generates pre-defined messages for delivery to other business management (e.g., ERP, accounting, and EDI) systems, and responds to ad hoc, online user inquiries and tracking requests. In a preferred embodiment, a model or state machine representation of the system is used.
