a definition of how to construct a particular bar code symbol
a subset of this EAN/JAN World Code system
The term barcode symbology can be thought of similarly to the way we think of the many languages we speak all around the world. There are many symbologies and they each have a vocabulary (character set) and a grammar or set of rules governing how we use the vocabulary. Some barcode symbologies are more appropriate for certain applications than others. Some symbologies encode only numbers 0 – 9, others encode numbers and upper case letters while others encode all 128 ASCII characters. One-dimensional (linear) symbologies have been around for years. Two-dimensional symbologies consist of stacked row symbologies and area symbologies.
The format in which the bar codes are printed on the bar code labels. (The number of lines, the length and width of each line).
A scheme for encoding data as bar code. Code 39, Interleaved 2 of 5, and Codabar are examples of different symbologies.
A defined method of representing numeric or alphabetic digits using bars and spaces that are easily scanned by computer systems. A specific type of bar code.
Representation or expression by means of a symbol. A barcode symbology is a class of bar code. For example, Code 39 is a symbology as is UPC.
Bar code language, i.e. Code39, UPC, EAN, including linear, stacked matrix and matrix bar codes.
the system of representing data in a bar code.
A combination of barcode characters including start/stop characters, quiet zones, data characters and check characters required by a particular type which form a complete scannable entity.
