A production line management system based on RFID technology applies advanced RFID technology in production lines, transfer and temporary storage warehouses, using reusable RF electronic tags and readable/writable data areas to write product information into RFID electronic tags. Readers are installed at offline workstations and warehouse entrances and exits to automatically write and collect product information at various locations through reading and writing tag information, and share data information with other IT systems. The information is also displayed on the screen to prompt production line operators, thereby tracking and managing the entire process of semi-finished products from offline to warehouse transfer, temporary storage, and re online production. This can ensure the correspondence of batch and box numbers between production lines, and each production line can complete production tasks without errors and record them. Important information during the production process, It can provide basic data services for future quality information traceability
