Barcode reader is a device that scans and interprets barcode labels affixed to products. It consists of a light source, a lens, and a photosensitive element that captures the barcode image. When the scanner is passed over the barcode, the light reflects off the black and white lines, generating electrical signals.
These signals are converted into a series of numbers and letters that represent the encoded information. Retailers employ barcode readers to quickly and accurately retrieve product details, such as price, description, and stock levels, from a database. This technology enables efficient point-of-sale operations, inventory management, and product tracking, ultimately enhancing the overall productivity and accuracy of retail operations.
