The characteristics of QR code seal

When checking seals, it mainly based on seal numbers and supplemented by QR codes, which can accurately identify the authenticity of security seals. If the seals have been exchanged and replaced with seals from other manufacturers during transportation, you can use our company's technology and equipment to identify the authenticity through QR code scanning.
