Warehouse management relies on accurate goods tracking. Using RFID tags and readers provides real-time tracking of inventory as goods move through the warehouse. This allows automatic updating of inventory records to reduce errors from manual data entry. The system uses RFID tags attached to goods and readers located at passageways and in handheld devices. Tags contain identifying information about each item. Readers automatically scan tags and update inventory databases as goods are received, stored, picked, and shipped. Regular scans with handheld readers allow checking of inventory levels and detection of any errors.
