Codabar
Codabar is a linear 1D barcode and can encode the digits 0 through 9, six symbols (-:.$/+), and the start/stop characters A, B, C, D, E, *, N, or T. The start/stop characters must be used in matching pairs and may not appear elsewhere in the barcode.
Uses:
Codabar is used in blood banks, libraries, overnight package delivery industries, and other information processing applications.
Code 11
Code 11 is a linear 1D barcode. The character set includes the digits 0 through 9, a dash ( - ), and a start/stop code. Each character is encoded with three bars and two spaces. Of these five elements, there may be two wide and three narrow, or one wide and four narrow. Wide elements represent a binary 1 while narrow elements represent a binary 0.Two check digits, named C and K, are used; often only the first check digit (C) is used when the length of the data is 10 characters or fewer.
Uses:
Code 11 is used primarily for labeling telecommunications equipment
Code 3 of 9
The Code 39 character set includes the digits 0-9, the letters A-Z (upper case only), and the following symbols: space, minus (-), plus (+), period (.), dollar sign ($), slash (/), and percent (%). A special start/stop character is placed at the beginning and end of each barcode. The barcode may be of any length, although more than 25 characters really begins to push the bounds.Each character consists of 9 elements: 5 bars and 4 spaces. Each character includes 3 wide and 6 narrow elements. Characters are separated by an inter-character gap which is the same width as a narrow bar.
Uses:
Code 39 is widely used in many industries and is the standard for many government barcode specifications, including the U.S. Department of Defense.
Industrial 2 from 5
Industrial 2 of 5 is a linear 1D barcode. Industrial 2 of 5 numeric-only barcode that has been in use a long time. Unlike Interleaved 2 of 5, all of the information is encoded in the bars; the spaces are fixed width and are used only to separate the bars. The code is self-checking and does not include a checksum.
Uses:
Interleaved 2 from 5
Each data character is composed of 5 elements, either 5 bars or 5 spaces. Of these 5 elements, two are wide and three are narrow. Adjacent characters are interleaved, alternating the spaces from one character with the bars of the other.
Uses:
Interleaved 2 of 5 is a numeric-only barcode widely used in warehouse and industrial applications. The data must consist of an even number of digits.
Matrix 2 from 5
Matrix 2 of 5 is a linear 1D barcode. Matrix 2 of 5 is self-checking numeric-only barcode. Unlike Interleaved 2 of 5, all of the information is encoded in the bars; the spaces are fixed width and are used only to separate the bars.
Uses:
Matrix 2 of 5 is used primarily for warehouse sorting, photo finishing, and airline ticket marking.
Plessey
Plessey is a linear 1D barcode. The MSI Plessey Code is is a pulse-width modulated non-self checking code. Each character is represented by 4 bars; a narrow bar represents a binary 0 and a wide bar represents a binary 1. The bars have the binary weights 8-4-2-1. It is possible to encode the digits 0 through 9 and the letters A through F, although this code is most often used just for numeric information. The start character is a single wide bar, and the stop character is two narrow bars.
Uses:
Plessey is used in libraries, and is often used for retail grocery shelf marking.
Code 128
Code 128 is a linear 1D barcode. The Code 128 character set includes the digits 0-9, the letters A-Z (upper and lower case), and all standard ASCII symbols and control codes. The codes are divided into three subsets A, B, and C. There are three separate start codes to indicate which subset will be used; in addition, each subset includes control characters to switch to another subset in the middle of a barcode. Subset A includes the standard ASCII symbols, digits, upper case letters, and control codes. Subset B includes standard ASCII symbols, digits, upper and lower case letters. Subset C compresses two numeric digits into each character, providing excellent density.
Uses:
Code 128 provides excellent density for all-numeric data and good density for alphanumeric data.
EAN 8
EAN-8 is a shortened version of the EAN-13 code. It includes a 2 or 3 digit country code, 4 of 5 data digits (depending on the length of the country code), and a checksum digit. While it is possible to add a 2-digit or 5-digit extension barcode, the primary purpose of the EAN-8 code is to use as little space as possible.
Uses:
EAN-8 symbols are limited in each country and can be used to specifically identify a particular product and manufacturer. Since a limited number of EAN-8 codes are available in each country, they are issued only for products with insufficient space for a normal EAN-13 symbol.
EAN 13
The symbol encodes 13 characters: the first two or three are a country code which identify the country in which the manufacturer is registered (not necessarily where the product is actually made). The country code is followed by 9 or 10 data digits (depending on the length of the country code) and a single digit checksum. 2-digit and 5-digit supplemental barcodes may be added for a total of 14 or 17 data digits.
Uses:
EAN-13 is used world-wide for marking retail goods.
UPC-A
UPC-A encodes 12 numeric digits. The first digit identifies the numbering system being used:
0: regular UPC codes
1: reserved
2: random weight items marked at the store
3: National Drug Code and National Health Related Items code
4: no format restrictions, for in-store use on non-food items
5: for use on coupons
6: reserved
7: regular UPC codes
8: reserved
9: reserved
The next group of 5 digits identifies the manufacturer. This number is assigned by the Uniform Code Council (UCC). The next 5 digits identify the particular product and are assigned by the manufacturer. The last digit is a Modulo 10 checksum.
UPC-E
In addition to the requirement that the first digit of the barcode (number system) must be zero, there are four rules that determine what UPC codes can be printed using the compressed UPC-E format:
If the last 3 digits of the manufacturer's number are 000, 100, or 200, the valid product code numbers are 00000 - 00999 (1,000 numbers).
If the last 3 digits of the manufacturer's number are 300, 400, 500, 600, 700, 800, or 900, the valid product code numbers are 00000 - 00099 (100 numbers).
If the last 2 digits in the manufacturer's number are 10, 20, 30, 40, 50, 60, 70, 80, or 90, the valid product code numbers are 00000 - 00009 (10 numbers).
If the manufacturer's number does not end in zero, the valid product code numbers are 00005 - 00009 (5 numbers).
Uses:
UPC-E is used for marking products which are sold at retail in the USA. UPC-E are used for labeling small items.
