During product manufacturing, unique identifiers such as standard digital codes, 1D barcodes, 2D QR codes, or RFID tags are used to assign each item a unique "identity." This establishes a standardized data framework from the origin of production and captures authentic, verifiable full lifecycle product data. By integrating supply chain operations, connecting end-users, and reaching consumers, this system enables end-to-end traceability. Consequently, after marking, barcode quality verification and OCR reading are essential to ensure accuracy and reliability.
