Interleaved 2 of 5 (also called I-2/5 and ITF) is suitable for encoding
general purpose all-numeric data. Reference symbology for UCC/EAN Shipping
Container Symbol. Character encodation, reference decode algorithm and
optional check character calculation are included in this document. This
specification is intended to be significantly identical to corresponding
Commission for European Normalization (CEN) specification.
(6/93) ANSI/AIM BC1-1995, Uniform Symbology
Specification - Code 39
Code 39 (Also Called Code 3 of 9) is suitable for encoding general
purpose alphanumeric data. Reference symbology for many industry
standards. Character encodation (standard and optional full ASCII),
reference decode algorithm and optional check character calculation are
included in this document. This specification is intended to be
significantly identical to the corresponding Commission for European
Normalization (CEN) specification.
Codabar encodes all-numeric data and has four unique start/stop
characters which can convey additional information. Character encodation
(including traditional Codabar), reference decode algorithm and optional
check character calculation are included in this document. This
specification is intended to be significantly identical to the
corresponding Commission for European Normalization (CEN) specification.
More condensed than Code 39, Code 128 is suitable for encoding general
purpose alphanumeric and full ASCII data and provides high information
density encodation of numeric data strings. A new feature permits
encodation of extended ASCII for non-English language characters.
Reference symbology for UCC/EAN Serial Shipping Container Symbol and all
UCC/EAN secondary identification symbols employing application
identifiers. Character encodation (code sets A, B, and C), reference
decode algorithm and optional check character calculation are included in
this document. This specification is intended to be significantly
identical to the corresponding Commission for European Normalization (CEN)
specification. (Detailed
Overview)
Code 93 offers higher information density for alphanumeric data than
either Code 39 or Code 128. Character encodation (including full ASCII),
reference decode algorithm and optional check character calculation are
included in this document.
Channel Code is a family of linear (one-dimensional) bar code symbols
designed for encoding strings of 2 to 7 digits in the least symbol length
possible. Reference decode algorithm and optional check calculation are
included in this document. There are six defined sizes of the symbols.
They range from "Channel 3" which can number up to 27 items in just 22 "X"
of total symbol length up to "Channel 8" which can number up to 7,742,863
items in a space equivalent to 42 "X". There are also a number 'composite'
symbol formats defined that offer enhanced capacity and/or security.
Channel Code symbols can be made autodiscriminatable from many other
symbologies, but they are not autodisriminatable from each other in a
reliable manner. It is strongly recommended that applications using
Channel Code select to use, and their readers be programmed to decode just
a single channel or composite format.
Telepen is a bar code symbology which enables the full 128 ASCII
character set to be encoded. Additionally it offers a compressed
numeric mode enabling numeric data to be encoded at twice the density of
the standard mode. IT is a wide-narrow symbology with a fixed 3:1
wide:narrow ratio.
