This allows for easy tracking, monitoring, and maintenance of devices, streamlining the management process. **

QR code traceability works by encoding information within the code itself, which can then be scanned and decoded using a smartphone or QR code reader. This information can include details about the product, such as its origin, manufacturing date, and batch number. When the QR code is scanned, the information is transmitted to a central database, allowing for real-time tracking and monitoring of the product throughout the supply chain. This traceability helps to ensure product authenticity, quality control, and can also be used for recalls or to provide consumers with more information about the product. **
