This paper presents the design and development of a low-cost edge computing system tailored for industrial barcode-driven traceability. The proposed solution integrates a Raspberry Pi–based embedded unit with programmable logic controller (PLC) signals to acquire, decode, and match barcode data in real time. Following software engineering principles, the system supports rapid barcode scanning and time-synchronized data transmission via an HTTP-based API, including integration with high-speed production workflows. A modular software architecture enhances flexibility, reliability, and scalability. Experimental results demonstrate a scan-to-database response time of less than 2.5 seconds and a matching accuracy exceeding 99.5%, validating the system’s viability for low-cost industrial settings.
