Barcode scanning is a technology used to electronically read and decode barcodes, which are visual representations of data in the form of parallel lines of varying widths and spacing. Barcode scanners use a light source to illuminate the barcode and a sensor to detect the reflected light pattern, which is then converted into an electrical signal. This signal is processed by a decoder, which identifies the barcode type and extracts the data encoded within it. Barcode scanning is commonly used in retail, inventory management, logistics, and healthcare to quickly and accurately identify and track products, assets, and records.
