What is a Barcode?
A barcode is a machine-readable optical label that stores data about the object it is attached to. Barcodes are widely used in retail, inventory management, shipping, libraries, healthcare, and many other industries to automate data entry and reduce errors.
History of Barcodes
The first barcode was scanned in 1974 on a pack of Wrigley's chewing gum. Since then, barcode technology has become a global standard for product identification and tracking.
How Barcodes Work
Barcodes consist of black bars and white spaces of varying widths. A barcode scanner reads the reflected light from the pattern and converts it into digital information, which is then sent to a computer or point-of-sale system.
Benefits of Using Barcodes
