Codabar
A discrete self-checking code with a character set consisting of start/stop
characters (A B C D or * T N E), digits 0 to 9, and these additional characters:
( - $ : / , +).
Code
Set of unambiguous rules specifying the way in which data may be
represented.
Codeword
In PDF417, a single group of bars and spaces (4 bars and 4 spaces, for a total
of 17 module widths) which represents one or more numbers, letters, or other
symbols.
Codeword Pd
(Codeword Percent
Decode)
Within a PDF417 symbol, the percentage of codewords which decoded
successfully; the number of good codewords divided by the total number of
codewords (data codewords plus error correction codewords).
Code Length
Number of data characters in a bar code between the start and stop
characters, not including those characters.
Code 128
A high density symbology which allows the interface controller to encode all
128 ASCII characters without adding extra symbol elements.
Code 3 Of 9
(Code 39)
A versatile and widely used alphanumeric bar code symbology with a set of
43 character types, including all uppercase letters, numerals from 0 to 9, and
7 special characters (- . / + % $ and space). The code name is derived from
the fact that 3 of 9 elements representing a character are wide, while the
remaining 6 are narrow.
Continuous Code
A bar code or symbol in which all spaces within the symbol are parts of
characters. There are no intercharacter gaps in a continuous code. The
absence of gaps allows for greater information density.
Country Flag
In EAN-8 and EAN-13 codes, two or three digits which appear immediately
following the left guard bar pattern.
Dead Zone
An area within a scanner's field of view, in which specular reflection may
prevent a successful decode.
Decode
To recognize a bar code symbology (e.g., UPC/EAN) and then analyze the
content of the specific bar code scanned. To translate the bar/space pattern
into defined characters within a defined symbology.
Decode Algorithm
A decoding scheme that converts pulse widths into data representation of the
letters or numbers encoded within a bar code symbol.
