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.
Code 93
An industrial symbology compatible with Code 39 but offering a full
character ASCII set and a higher coding density than Code 39.
Code Length
Number of data characters in a bar code between the start and stop
characters, not including those characters.
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.
CTS
Clear to send.
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.
Decode Algorithm
A decoding scheme that converts pulse widths into data representation
of the letters or numbers encoded within a bar code symbol.
Depth of Field
The range between minimum and maximum distances at which a
scanner can read a symbol with a certain minimum element width.
Digitized Bar Pattern
(DBP)
A digital representation of a decoded bar code.
Discrete 2 of 5
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.
Discrete Code
A bar code or symbol in which the spaces between characters
(intercharacter gaps) are not part of the code.
EAN
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.
Element
Generic term for a bar or space.
