Marking machines and scanner guns are essential tools in industrial and automation settings, designed for efficient identification, tracking, and data capture. Marking machines include laser engravers, dot peen markers, and inkjet printers, used for permanent labeling on metal, plastic, or other materials. Scanner guns, such as barcode and RFID readers, enable quick inventory management, asset tracking, and process automation. These devices enhance productivity, accuracy, and traceability in manufacturing, logistics, and warehouse operations.
