This article introduces the RFID handheld terminal (PDA), which integrates RFID reading and writing, barcode scanning and data processing. With the advantages of high-efficiency identification, real-time data synchronization and rugged durability, it is widely applied in file and asset management, warehousing and logistics, retail stores, manufacturing and equipment inspection.

RFID technology, via electronic ear tags and readers, enables full livestock traceability and intelligent management across breeding, epidemic prevention, and production processes, boosting efficiency and food safety in modern animal husbandry.
