Barcode Technology - Plessey Barcode               Hide the description

Plessey Code is a 1D linear barcode symbology based on pulse width modulation, developed in 1971 by The

Plessey Company plc, a British-based company. It is one of the first barcode symbology, and is still used in some rare libraries and for shelf tags in retail stores, in part as a solution to their internal requirement for stock control. The system was first used in the early 1970s by J.Sainsbury to identify all of its products on supermarket shelves for its product restocking system.

The chief advantages are the relative ease of printing using the dot-matrix printers popular at the time of the

code's introduction, and its somewhat higher density than the more common 2 of 5 and 3 of 9 codes. It has later led several variations as Anker Code by ADS Company, Telxon, and MSI (also known as Plessey modified). It is difficult to have the specifications for them nowadays and thus hard to tell the differences between them (except for MSI), because it was mainly available as a paper document and has since been discontinued..

Valid characters: 0123456789ABCDEF

Plessey 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.

Plessey is 1D barcode.

The barcode comprises:
the forward start code
the label / data digits
the check code, for error detection
the termination bar
the reverse start code

Plessey is variable with no fixed length.

Check digit:

The check code for error detection and correction is as CRC, using polynomial division. Is uses 2 characters, or 8 bits. The generator polynomial is {\displaystyle g(x)=x^{8}+x^{7}+x^{6}+x^{5}+x^{3}+1} g(x)=x^{8}+x^{7}+x^{6}+x^{5}+x^{3}+1 with n=8, in binary "111101001".

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 a barcode system can make the working process simple and easy, so it can reduces the employee training time. It only takes a few minutes to master the barcode scanner to collecting data, employees no need to familiar with the entire inventory or pricing process. This also reduces the cost of employee training.

The barcode system is very versatile, it can be used for any necessary data collection. This may include pricing or inventory information or management information service system. In addition, because barcodes can be affixed to almost any surface, they can be used not only to track the product itself, but also to track the production process, shipments and equipments.

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 Plessey Barcode


What is the historical origin of the Plessey barcode?

Plessey Code is a one-dimensional linear barcode symbology system based on pulse width modulation. It was developed by the British Plessey Company plc in 1971 and was officially used in May 1971. It is mainly used in library management.

It was one of the earliest barcode symbologies and is now still rarely used in shelf labels in some libraries and retail stores, partly as a solution to internal requirements for inventory control.

It is a barcode symbol represented by numbers 0-9, with a start character and an end character. Plessey Corporation is an electronics, defense and telecommunications company founded in 1917 and later spun off and acquired. It was also the first company to design an industrial-grade secure computer. Now, Plessey Company is mainly engaged in the research and development of micro-LED display technology.

J.Sainsbury's first used the system in the early 1970s to identify all products on supermarket shelves for its product replenishment system.

The main advantages are that it is relatively easy to print on the dot matrix printers that were popular when this code was introduced, and that it is slightly denser than the more common 2 of 5 and 3 of 9 codes.

It later had several variants called Anker Code (also known as Plessey modifications) led by ADS Corporation, Telxon, and MSI.


Structural characteristics of Plessey barcode

It is a barcode symbol represented by numbers 0-9, with a start character and an end character.

It uses a special encoding method in which each character consists of four bars and four spaces.

Its check digit is obtained by summing the odd digits of all characters, multiplying by 2, adding the even digits of all characters, and finally taking the single digit.

Its bar-to-space ratio is 1:3:2:1, that is, the ratio of narrow bars, narrow spaces, wide bars, and wide spaces.


What are the advantages and disadvantages of Plessey barcodes?


It's easy to print on a dot-matrix printer, can be of any length, and tells what products are on the shelf, how many should be on them and other relevant information.


It is currently considered obsolete, its encoding is complex, and its check digits are unreliable.
