A barcode reader is considered a direct input device because it captures data directly from a barcode and converts it into a digital format that can be processed by a computer or system. This process occurs in real-time, allowing for immediate data entry without the need for intermediary steps. By scanning barcodes, it eliminates manual data entry errors and enhances efficiency in tracking inventory or processing transactions.
