Where is a barcode scanner commonly used in daily life?

Answer and explanation

Correct answer: Reading product information and price at a shop billing counter

A barcode scanner is an input device that reads the pattern printed on a product and sends its coded identification to a computer or point-of-sale system. The system can then retrieve the product name, price, and stock information, making checkout faster and more accurate. Option A is correct because retail billing is the common daily-life use. Options B, C, and D do not normally require barcode scanning and are unrelated to product identification.
