Bulk Barcode Generator for Codebar

Barcode Technology - Codebar Barcode               Hide the description

Codebar is primarily used for medical purposes. It is a numeric code with some additional special characters

(0..9 and - $ : / . +). There are four different start and stop signs defined. These start and stop signs are used in our software as A, B , C and D. They are only valid at the beginning and the end of the code. They can be used to transport additional information.

Valid characters: 0123456789-$:/.+

Old format used in libraries and blood banks and on airbills (out of date, but still widely used in libraries)

Codebar is one of the many barcode formats currently in use.

A Barcode is a method of representing data in a visual, machine-readable form.

The barcode formats has two categories:

One-dimensional (1D) --- Barcodes represented data by varying the widths and spacings of parallel lines.

Two-dimensional (2D) --- Using rectangles, dots, hexagons and other geometric patterns to represented data.

Check digit:

Because Codabar is self-checking, most standards do not define a check digit.Some standards that use Codabar will define a check digit, but the algorithm is not universal. When all 16 symbols are possible, a simple modulo-16 checksum is used. The values 10 through 19 are assigned to the symbols –$:/+.ABCD, respectively.

Human Readable:

Most barcodes display their corresponding values below them, which makes it possible to human read and manually  enter the barcode values into the equivalent system when the barcode label is worn out and cannot be read by the barcode scanner.

The Advantages of using barcodes:

Using Barcode system eliminates the possibility of human error. The error rate of manually entering data is
significantly higher than that of scan barcodes. Barcode scanning is fast and reliable, and it takes much less time than manual data entry. Especially when using a QR code, hundreds of characters can be read and entered into your system instantly.

When barcodes are used in management information systems, they can promote better decision-making. Because data is obtained quickly and accurately, you can quickly obtain a full range of information for the entire company or organization, so it is possible to make more informed decisions. Better decisions can ultimately save time and money.

Barcodes are cheap and user-friendly, providing an indispensable tool for tracking data from pricing to inventory. The end result of a comprehensive bar code system is reduced overhead.

FAQ About Codabar Barcode

What is the historical origin of the Codabar barcode?

Codabar is a linear barcode symbology developed by Pitney Bowes Corp in 1972.

It and its variants are also known as Codeabar, Ames Code, NW-7, Monarch, Code 2 of 7, Rationalized Codabar, ANSI/AIM BC3-1995, or USD-4.

Although Codabar has not yet registered U.S. federal trademark status, its hyphenated variant, Code-a-bar, is.

The Codabar barcode is a linear barcode that is widely used wherever serial numbers are required. The Codabar is designed to be read accurately even when printing multi-part forms such as FedEx air waybills and blood bank forms on dot matrix printers. As of 2007 Variations of these tables are still in use. Although newer symbologies contain more information in smaller spaces, Codabar has a large installed base in libraries.

Codabar codes can even be printed using a typewriter-like impact printer, allowing many codes with consecutive numbers to be created without the use of computer equipment. Each time a code is printed, the printer's imprint mechanically advances to the next number, like a mechanical mileage counter.

Structure of Codabar barcode

Codabar has 4 bars and 3 spaces (total 7 cells), each narrow or wide width represents a character (letter). 7 bars and spaces represent one character. It contains a 20-bit character set: the numbers "0-9", the four English capital letters A, B, C, and D, and 6 special characters ("-", ":", "/", ".", " +", "$"). There is any one of A, B, C or D (a, b, c or d) at the beginning and end of the barcode (start/terminator).

It consists of 20 character sets, including the numbers "0-9", the four English capital letters A, B, C, and D, and 6 special characters ("-", ":", "/", "." , "+", "$").

It uses 4 bars and 3 spaces (a total of 7 cells) to represent a character, and each bar or space can be narrow or wide.

It uses asterisk (*) as start and end characters.

What industries are Codabar barcodes used in?

Codabar barcode is a linear barcode that is widely used in areas that require serial numbers, such as blood banks, door-to-door delivery service orders, and membership card management.

It contains a 20-bit character set: the numbers "0-9", the four English capital letters A, B, C, and D, and 6 special characters ("-", ":", "/", ".", " +", "$").

Codabar barcodes are widely used in industry, mainly in the following aspects:

Medical and health care: used in blood banks, hospitals, drug management, etc.

Logistics transportation: used for door-to-door delivery service orders, courier tracking numbers, air luggage, etc.

Library: used for book coding, borrowing management, etc.

Membership card: used for membership card management, points redemption, etc.

Others: used for bills, certificates, coupons, etc.

Application examples: Codabar for library management

Each book has a unique barcode label, which is used to represent the book's number, classification, author, publisher and other information.

The library management system can record the borrowing, returning, querying, statistics and other operations of books by scanning barcodes.

Codabar's start and end characters can be used to distinguish different libraries or different book types.

The advantages of Codabar for library management are:

It can improve library efficiency and accuracy and reduce human errors and omissions.

It can easily classify, retrieve, inventory and store books.

It saves library space and costs because it does not require the use of complex equipment and materials.

Who developed the Codabar barcode standard? Why develop this standard?

The standard for Codabar barcodes is developed by the American National Standards Institute (ANSI) and the International Association of Automatic Identification Manufacturers (AIM), numbered ANSI/AIM BC3-1995.

The purpose of formulating this standard is to unify the encoding rules, print quality, reading performance and other aspects of Codabar barcodes to facilitate compatibility and exchange between different devices and systems.

What are the advantages and disadvantages of Codabar barcodes?

Advantage:

It can represent numbers, letters and special characters, and has strong coding capabilities.

Bars and spaces of any width can be used, making printing more tolerant.

You can use the four letters A, B, C, and D as the start/terminator to easily distinguish different application scenarios.
It can be produced and read using simple printers and scanners.

It has higher reliability because it uses more bars and spaces to represent a character and does not require check digits.

Shortcoming:

Each character requires 9 bars and spaces, takes up a lot of space, is not suitable for representing long data, and only has a 20-character set.

It does not support non-Latin characters such as Chinese and has low international applicability.

It cannot represent lowercase letters or other symbols..
