Barcode Technology - Plessey Barcode               Hide the description

The MSI Plessey barcode has been designed by the Plessey Company, England in 1971. It has been used in libraries and stores.

The code can display only the number 0-9 and has no fixed length. Today this type of code is outdated and is no longer used. Because of this most barcode scanners can not recognize this type of code.

Valid characters: 0123456789

MSI 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.

Check digit:

No check digit.

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.

The barcode system provide better data. Because a barcode can store various information such as inventory and pricing, especially when using QR Code, it can store thousands of characters, so the data stored in the barcode can be quickly obtained by the barcode reader, this fast turnaround ensures that time is not wasted on data entry or retrieval. In addition, the barcode can be customized to include other relevant information as needed. They provide fast and reliable data for various applications.

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.

The purpose of this standard is to provide a digital barcode for use on shelves in supermarkets, storage warehouses and other storerooms. This makes it easy to identify the products on the shelves, the quantities that should be placed and other relevant information.

What is the difference between MSI Plessey barcode and Plessey barcode?

MSI Plessey barcode is a variant of Plessey barcode, named after MSI Data Corporation.

MSI Plessey barcodes use a binary format, with black stripes representing "1" and spaces representing "0". Plessey barcode uses quaternary format, each character includes 4 bars and 4 spaces, and each pair of bars and spaces constitutes an information bit.

MSI Plessey barcodes can only encode numbers, not letters. Plessey barcodes can encode numbers and letters.

What are the advantages and disadvantages of MSI Plessey barcodes?

Advantage:

MSI Plessey barcodes are available in any length and can be used to encode large amounts of information.

Shortcoming:

MSI Plessey barcodes can only encode numbers, not letters. Binary formats are also inefficient and error-prone.

What are the application scenarios of MSI Plessey barcodes?

Shelves in supermarkets, storage warehouses and other storerooms used to identify products, quantities and information.

Library and retail applications for managing books and merchandise.
