What is a Barcode?

A barcode is a method of representing data in a visual, machine-readable form. Originally, barcodes represented data by varying the widths and spacings of parallel lines, and may be referred to as linear or one-dimensional (1D) barcodes.

Barcodes are widely used in retail, logistics, inventory management, and many other industries. They enable quick and accurate data entry, reduce human error, and improve efficiency in various business processes.
