PDA handheld terminal NFC reading: handheld PDA for product anti-counterfeiting error-proof traceability solution

The error-proof traceability system needs to adopt a unified information means to install the one-dimensional/two-dimensional barcode, RFID and other information record body on the assembly line, and through the real-time scanning and comparison of the PDA handheld terminal, whether the assembly meets the requirements through the integrated machine or the touch screen. And send real-time data from the assembly process to the system logging server.

The key information is collected and associated with the door panel information, and a unified key piece barcode rule is established. The key piece barcode can be traced through the PDA handheld terminal to know which supplier, production date, production batch and the like. This is convenient for batch management and post-quality traceability. All key information related to it can be traced through any key bar code information.
