Later applications software became available for devices that could read images, such as smartphones with cameras. Later two-dimensional (2D) codes were developed, using rectangles, dots, hexagons and other geometric patterns in two dimensions, usually called barcodes although they do not use bars as such.īarcodes originally were scanned by special optical scanners called barcode readers. Originally barcodes systematically represented data by varying the widths and spacings of parallel lines, and may be referred to as linear or one-dimensional (1D). Optimal when the barcode size needs to be minimized. Reduced size and capacity of a normal QR code. ASCII character set supported by using combinations of 2 characters. High capacity, optimal for small packages.Ĥ3 characters allowed. High capacity, symbol size adjusts automatically depending on the amount of input data. Adaptable size to the amount of encoded data.
Used on 135 film, for ITF-14 barcodes, and on packaging.Ī matrix barcode readable by QR scanners and smartphones. Small package marking where an EAN-13 barcode would be too large.Ī variant of Code 128 - it automatically inserts a FNC1 character after the initial character. Widely used in libraries and package delivery systemsĭouble density data encoding, ASCII character set supported.įully alphanumeric barcode for use with data-entry systems.Ģ8 ASCII character set including asterisks supportedĮuropean Article Number, used for global retail. A self-checking and binary level linear barcode symbology with no check sum digit appended.
