Symbologies are different ways of representing data in bar and space patterns. Some symbologies use only two different widths of bar and space while others use four. Different symbols have been designed to meet different data encoding requirements, and some are designed to be readable when printed onto poor quality substrates. The barcodes of the GS1 System are intended for use in open trade, while others such as Code 39 and Code 128 are available for sector-specific or in-house use.
