Which device is used in shops to read a product code?

Answer and explanation

Correct answer: Barcode reader

The governing concept is input technology used for automatic identification. A barcode reader scans the pattern of bars and spaces printed on a product and converts it into digital data for the shop’s billing system. Thus, option D is correct. A webcam captures general images, a keyboard requires manual typing, and a projector displays information. None of these is specifically designed to decode retail barcodes.
