A barcode is an optical machine-readable representation of data‚ which shows data about the object to which it attaches. Originally‚ barcodes represented data by varying the widths and spacings of parallel lines‚ and may be referred to as linear or 1 dimensional (1D). Later they evolved into rectangles‚ dots‚ hexagons and other geometric patterns in 2 dimensions (2D). Although 2D systems use a variety of symbols‚ they are generally referred to as barcodes as well. Barcodes originally were scanned
