Barcode

A barcode is a machine-readable representation of data that encodes information in a visual pattern of parallel lines or spaces, or other shapes, which can be scanned and interpreted by barcode readers. Barcodes are commonly used to track and manage inventory, streamline point-of-sale transactions, and facilitate the logistics and supply chain processes. There are various types of barcodes, including linear barcodes (such as the Universal Product Code (UPC) and the European Article Number (EAN)) and two-dimensional barcodes (such as QR codes). Barcodes improve accuracy and efficiency by reducing human error in data entry, speeding up transaction processing, and enhancing the ability to monitor and control inventory. They are widely used across various industries, including retail, healthcare, manufacturing, and logistics.
