1D/9D code readers are industrial-grade barcode scanners used across various sectors for efficient data capture. These devices are typically manufactured by companies like Honeywell (USA), Zebra Technologies (USA), Datalogic (Italy), and Keyence (Japan). They serve industries such as manufacturing, logistics, retail, and healthcare, enabling quick scanning of 1D barcodes (linear) and 2D codes (QR, Data Matrix, etc.). Popular models include handheld, fixed-mount, and mobile readers, often integrated with PLCs or ERP systems for inventory tracking and process automation. Brands like Cognex (USA) also offer advanced vision-based code reading solutions for industrial automation.
