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.

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.

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.

DISCRETE CODE

- A bar code or symbol in which the spaces between

characters (intercharacter gaps) are not part of the 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.

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.

HOST COMPUTER

- A computer that serves other terminals in a network,

providing such services as computation, database access, supervisory
programs, and network control.

IEC

- International Electrotechnical Commission. This international agency

regulates laser safety by specifying various laser operation classes based on
power output during operation.
