Direct Part Marked (DPM) 2D codes are commonly used for permanent identification on industrial components such as metal parts, electronic devices, and precision-machined products. However, these codes are often difficult to read due to low contrast, surface curvature, machining marks, oil contamination, or uneven engraving quality.

A high-performance handheld DPM scanner enables reliable capture of difficult-to-read 2D codes by enhancing image processing and decoding performance under challenging conditions. It ensures stable code reading even on low-quality or partially damaged markings, allowing accurate part identification during production, inspection, and maintenance operations. This improves data capture reliability, reduces manual intervention, and supports consistent industrial traceability workflows.
