Revision: 2.0 , technical changes excepted
A digit used to verify a correct symbol decode. The scanner inserts the decoded
data into an arithmetic formula and checks that the resulting number matches the
encoded check digit. Check digits are required for UPC but are optional for other
symbologies. Using check digits decreases the chance of substitution errors when
a symbol is decoded.
An option which inserts a space after the 1st, 5th, and 10th characters of a 14-
characterCodabar symbol. Length includes start and stop characters.
A discrete self-checking code with a character set consisting of digits 0 to 9 and six
additional characters: ( - $ : / , +).
A high density symbology which allows the controller to encode all 128 ASCII
characters without adding extra symbol elements.
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.
An industrial symbology compatible with Code 39 but offering a full character ASCII
set and a higher coding density than Code 39.
Number of data characters in a bar code between the start and stop characters,
not including those characters.
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.
Clear to send.
An area within a scanner's field of view, in which specular reflection may prevent a
successful decode.
To recognize a bar code symbology (e.g., UPC/EAN) and then analyze the content
of the specific bar code scanned.
A decoding scheme that converts pulse widths into data representation of the
letters or numbers encoded within a bar code symbol.
The range between minimum and maximum distances at which a scanner can read
a symbol with a certain minimum element width.
A digital representation of a decoded bar code.
A binary bar code symbology representing each character by a group of five bars,
two of which are wide. The location of wide bars in the group determines which
character is encoded; spaces are insignificant. Only numeric characters (0 to 9)
and START/STOP characters may be encoded.
A bar code or symbol in which the spaces between characters (intercharacter
gaps) are not part of the code.
European Article Number. This European/International version of the UPC provides
its own coding format and symbology standards. Element dimensions are specified
metrically. EAN is used primarily in retail.
