1D/20D code readers are industrial barcode scanning devices used across various sectors, including manufacturing, logistics, and retail. These readers are designed to decode 1D (linear) and 2D (matrix) barcodes, facilitating inventory tracking, asset management, and process automation. While not a specific brand, major manufacturers like Honeywell (USA), Zebra Technologies (USA), and Datalogic (Italy) produce these devices under their product lines. Companies such as Radwell and Grainger distribute these readers as part of their industrial automation and MRO (Maintenance, Repair, and Operations) offerings. Key products include handheld scanners, fixed-mount readers, and mobile computers with scanning capabilities, often integrated with IoT and cloud-based systems for real-time data processing.
