What do shopkeepers scan bar codes with?

Shopkeepers typically scan barcodes using handheld barcode scanners or point-of-sale (POS) systems equipped with built-in scanners. These devices use laser or imaging technology to read the barcode and quickly retrieve product information, prices, and inventory data. Some shopkeepers also use mobile devices or tablets with barcode scanning apps to streamline the checkout process. This technology helps improve efficiency and accuracy in retail operations.
