Bar code definition

Barcode is a machine-readable code in the form of numbers and a group of parallel lines with varying width and spacing which is generally used for identifying a product.

Barcodes are generally scanned by a type of optical scanners called barcode readers. Though a combination of scanner/camera and an interpretive software can be used to perform the same task done by barcode reader.

Fact: The very first scanning of the Universal Product Code (UPC) barcode was done on a pack of Wrigley Company chewing gum in June 1974 at Marsh’s supermarket in Troy, Ohio.
