Correct Answer: Barcode reader
Solution : The correct option is a Barcode reader.
A barcode reader is typically considered an input device rather than an output device. It is used to input data by scanning and reading information from barcodes and translating the visual code into a digital format that can be used by a computer or other systems. Therefore, a barcode reader is not an output device.
