ABOUT Bar Codes



Bar Codes That NapTags Currently Offers…

2-D (Two Dimensional) - contain more information than conventional one dimensional linear bar codes. Conventional bar codes get wider as more data is encoded. 2D bar codes make use of the vertical dimension to pack in more data. 2D bar codes have become possible as auto scanning CCD and laser scanners have replaced the original 'light pen' type of scanner. PDF417 is firmly established as the number one choice for many 2D applications. Data is encoded in both the horizontal and vertical dimensions. As more data is encoded the size of the bar code can be increased in both the horizontal and vertical directions thus maintaining a manageable shape for easy scanning.

Codabar - A self-checking, discrete bar code symbology that has these 16 characters in its set: 0 to 9, dollar sign ($), colon (:), slash (/), period (.), plus (+), and minus (-). Codabar is commonly used in libraries, blood banks, and air-parcel express applications. The American Blood Commission (ABC) Codabar requires that you retain the start/stop code digits when processing a Codabar symbol. The maximum density for a Codabar symbol is 12.8 characters per inch.

______________________________

Code 11 - is used primarily for labeling telecommunications equipment. 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. The check digits are the result of a Modulo 11 division of the sum of the products of each digit times a weight factor. The weights for the C check digit range from 1 to 10 while the weights for the K check digit range from 1 to 9. Weights start at the right end of the data and increment towards the left. The dash character has a value of 10 for purposes of check digit calculation

Code 128 - is a very high density alphanumeric bar code. The symbol can be as long as necessary to store the encoded data.It is designed to encode all 128 ASCII characters, and will use the least amount of space for data of 6 characters or more of any 1-D symbology. Each data character encoded in a Code 128 symbol is made up of 11 black or white modules. The stop character, however,is made up of 13 modules. Three bars and three spaces are formed out of these 11 modules. Bar and spaces can vary between 1 and 4 modules wide. The symbol includes a quiet zone (10 x-dimensions), a start character, the encoded data, a check character, the stop character, and a trailing quiet zone (10 x-dimensions). For optimum hand-scanning with a contact reader, the quiet zone should be at least 0.25 inches.

Code 39 (aka USS Code 39, Code 3/9, Code 3 of 9, USD-3, Alpha39) - The first alpha-numeric symbology that originally encoded 39 characters (now 43) including uppercase letters (A - Z), digits (0 - 9) and a few special characters like the $ sign. The entire ASCII character set can be encoded using Code 39's Full ASCII mode. The bar code does not contain a check digit but is considered self-checking because a single erroneously decoded bar can not generate another valid character. The code has very low data density compared to other 1D codes which does not make it feasible for small space applications.

______________________________

Code 39 Extended - The extended 3 of 9 code is a general-purpose code that can code any ASCII character (any character you can enter from the keyboard by normal means). This code is double the size of the standard Code 39 as it uses two code characters for each of the 128 ASCII characters. As with the standard Code 39, data can be of any length.

______________________________

Code 93 - also called USS-93) is a slight variation of Code 39, designed to improve Code 39 to obtain denser code. Code 93 encodes 47 ASCII characters and is a continuous symbology. Code 93 can represent alpha-numeric data and is self-checking variable-length code. Applications Mainly used in manufacturing, military, and health applications. Benefits Code 93 being denser than Code 39, can be used on smaller products. In addition it has two check digits for error detection. Limitations Although Code 93 is considered more robust than Code 39, it is not as widely used as Code 39.

EAN 13 EAN-13 - is used world-wide for marking retail goods. 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 bar codes may be added for a total of 14 or 17 data digits.

______________________________

EAN 8 - is a bar code and is derived from the longer European Article Number (EAN-13) code. It was introduced for use on small packages where an EAN-13 bar code would be too large; for example on cigarettes, pencils (though it's not commonly used for pencils) and chewing gum packets.EAN-8 bar codes may be used to encode GTIN-8s which are another set of product identifiers from the GS1 System. It begins with a 2 or 3 digit GS1 prefix (which is assigned to each national GS1 authority) 5 or 4-digit item reference element depending on the length of the GS1 prefix), and a checksum digit. EAN-8 codes are common throughout the world, and companies may also use them to encode RCN-8s (8-digit Restricted Circulation Numbers) used to identify own-brand products which are only sold in their stores. These are formatted as 0xxx xxxx or 2xxx xxxx.

EAN.UCC 128 - The purpose of GS1-128 (formerly known as UCC-128 or EAN-128) is to establish a standard way of labeling a package with more information than just a product code. It provides supplemental information such as batch number and "use before" dates. There are two main components of UCC/EAN/GS1-128: the data with its Application Identifier and the bar code symbology used to code the data. The bar code symbology is code 128. The difference is the use of defined Application Identifiers with data encoded into the code 128 symbol.

______________________________

GS1 Bar Codes - are certainly the most well-known and universally recognizable part of the GS1 system of standards. Ever since they were invented over thirty years ago, GS1 has been building and managing bar code standards that enable businesses and organizations around the world to automatically identify products, pallets and places.GS1 Bar Codes enable businesses to manage the supply chain more efficiently.

Industrial 2 of 5 - The Industrial Code 2 of 5 bar code is a low-density numeric bar code that does not require a checksum.It is a non-interleaved barcode that is easier to print than the Interleaved 2 of 5 barcode because interleaving is not required. # The symbology of the Industrial Code 2 of 5 character set consists of bar code symbols representing the numbers0-9, the start character and the stop character. In the code 2 of 5 bar code fonts, the parentheses are used for start and stop characters. For example, to scan the numbers 1234, just type and print (1234)

Intelligent Mail - The Intelligent Mail bar code (formerly known as the 4-State Customer Bar code) is the next generation of USPS® bar code technology used to sort and track letters and flats. Intelligent Mail bar code technology, among other things,combines the capabilities of the POSTNET™ bar code and the PLANET Code® bar code into one unique bar code.

______________________________

Interleaved 2 of 5 (also called I 2 of 5) - is a numbers-only bar code. The symbol can be as long as necessary to store the encoded data. The code is a high density code that can hold up to 18 digits per inch when printed using a 7.5 mil X dimension. A check digit is optional.The "Interleaved" part of the name comes from the fact that a digit is encoded in the bars and the next digit is encoded in the spaces. The encoded digits are "Interleaved" together. There are five bars, two of which are wide and five spaces,two of which are wide.

ISBN 10 - The International Standard Book Number (ISBN) is a unique[1][2] numeric commercial book identifier based upon the 9-digit Standard Book Numbering (SBN) code created by Gordon Foster, now Emeritus Professor of Statistics at Trinity College Dublin,[3] for the booksellers and stationers W.H. Smith and others in 1966.[4] The 10-digit ISBN format was developed by the International Organization for Standardization and was published in 1970 as international standard ISO 2108.[4] (However, the 9-digit SBN code was used in the United Kingdom until 1974.) Currently, the ISO’s TC 46/SC 9 is responsible for the ISBN. The ISO on-line facility only refers back to 1978.[5]

______________________________

ISBN 13 - Since 1 January 2007, ISBNs have contained 13 digits, a format that is compatible with Bookland EAN-13s.[6] Occasionally, a book may appear without a printed ISBN if it is printed privately or the author does not follow the usual ISBN procedure; however, this is usually later rectified.[7][dubious – discuss]A similar numeric identifier, the International Standard Serial Number (ISSN), identifies periodical publications such as magazines.

MSI (also known as Modified Plessey) - is a bar code symbology developed by the MSI Data Corporation, based on the original Plessey symbology. It is a continuous symbology that is not self-checking. MSI is used primarily for inventory control,marking storage containers and shelves in warehouse environments.

Planet - This US Postal Office uses a combination of two tracking numbers (the POSTNET code and PLANET code ) to track customer’s piece of mail. USPS confirm service provides delivery information about (1) Incoming hard-copy reply mail (Origin Confirm) and (2) Outbound mail going to customers ( Destination Confirm). A PLANET symbol have 12 or 14 digits. PLANET code symbology is the inverse of the POSTNET codes.

Postnet POSTNET - (Postal Numeric Encoding Technique) is a bar code symbology that is used by the United States Postal Service to assist in directing mail. The ZIP Code or ZIP+4 code is encoded in half- and full-height bars. Most often, the delivery point is added, usually being the last two digits of the address or PO box number. The bar code starts and ends with a full bar (often called a guard rail or frame bar and represented as the letter "S" in the USPS TrueType Font) and has a check digit after the ZIP or ZIP+4. The encoding table is shown on the right. Each individual digit is represented by a set of five bars, two of which are full bars (i.e. two-out-of-five code). The full bars represent "on" bits in a pseudo-binary code in which the places represent, from left to right: 7, 4, 2, 1, 0. (Though in this scheme, zero is encoded as 11 decimal, or "binary" 11000.)

______________________________

Telepen - can be used to represent the full range of ASCII characters. This covers the standard set of printable characters including numbers, capital and lower-case letters and punctuation marks as well as the complete set of non-printable control characters such as carriage-return, line-feed, horizontal tab, etc. Telepen can also be used to represent numeric data in double-density mode, where an ASCII character is re-interpreted as a pair of numeric characters. There is nothing in the bar code to distinguish between the 2 modes, and the interpretation of the data as ASCII or numeric is set only by the configuration of the reading device. Telepen systems have been implemented in many countries and very widely in the UK. Most Universities and other academic libraries use Telepen, as do many public libraries. Other users include the motor industry, Ministry of Defense and innumerable well-known organizations for many different applications.

UPC A - The UPC-A bar code is the most common and well-known symbology in the United States. You can find it on virtually every consumer goods in your local supermarket, as well as books, magazines, and newspapers. There are a number of UPC variants, such as UPC-E, UPC 2-digit Supplement, UPC 5-digit supplement. UPC-A encodes 11 digits of numeric data along with a trailing check digit, for a total of 12 digits of bar code data.

______________________________

UPC E - The UPC-E bar code is the short form representation of a UPC number. It reduces the data length from 12 digits to 6 digits by compressing the extra zeros. It is suited for identifying products in small packages.A UPC-E bar code has 6 digits with an implied number system 0. The first 5 digits are calculated based on a conversion algorithm described below. The last digit is the check digit of the original UPC-A symbol.
