Symbologies are systems of encoding data such that a scanner and/or a decoding system may together read and decode the data encoded in the barcode. Aside from the actual technique of encoding the bars and spaces, a number of technical specifications or characteristics define and separate one symbology from another. Each symbology represents a different barcode format.

Barcode technology is widely used across many industries. Most barcodes are machine-readable symbols that consist of vertical bars and spaces. The typical barcode also features quiet zones before and after, a start character, numerous data characters, numerous optional checkdigits and a stop character.
