2D Code Decoding Ability — Traceability Inspection for QR & Data‑Matrix Packaging

More export‑oriented pharmaceutical, cosmetic and electronic packaging adopt QR codes and Data‑Matrix codes for full‑chain traceability. KQ‑VD720 supports stable decoding of common 2D code formats inline on folder‑gluer production lines.High‑speed image‑acquisition hardware completes decoding within milliseconds even under carton minor vibration. Operators set code‑content rules on the touch panel; unreadable, damaged or wrong‑content 2D codes are marked as non‑conforming and ejected automatically.

This 2D‑code function runs together with print‑template checking and 1D‑barcode verification. Manufacturers realize multi‑indicator quality control through one single vision unit instead of purchasing multiple separate inspection devices.It is widely applied for medical cartons, 3C‑product outer boxes and export food packaging.

Factories satisfy strict traceability requirements of overseas brand clients, avoid return risks caused by invalid two‑dimensional codes and improve overall automation level of post‑press workflow.
