What is a barcodes function?

A barcode functions as a visual representation of data, typically in the form of parallel lines and spaces that can be scanned by barcode readers. It encodes information such as product identifiers, prices, or inventory data, enabling quick and accurate tracking and management of items in retail, logistics, and other industries. When scanned, the barcode translates the encoded data into a format that can be processed by computers, facilitating efficient data entry and inventory control.
