MSI Barcode

MSI (Modified Plessey) is a type of barcode that is used primarily in inventory management and tracking applications. It consists of a series of black and white bars, where each bar represents either a “0” or a “1”. The bars are arranged in pairs, with each pair representing a single binary digit.

MSI codes can encode both numbers and letters, making them a flexible and versatile form of product identification. They are commonly used in applications such as inventory management, where they can be used to track the movement of goods from the warehouse to the retail store or other distribution center.

One of the key benefits of using MSI codes is their ability to be read by a wide range of barcode scanners and other reading devices. This makes them a highly reliable and versatile form of product identification, which is essential for many inventory management and tracking applications.

MSI codes are also highly customizable, allowing businesses to tailor the codes to their specific needs. For example, businesses can use MSI codes to encode information such as product weights, dimensions, and SKU numbers. This flexibility makes MSI codes a powerful tool for managing inventory and logistics operations.

In addition to the standard MSI code, there are also variations such as the MSI Plessey code and the MSI Modified Plessey code. The MSI Plessey code uses a slightly different encoding method than the standard MSI code, while the MSI Modified Plessey code uses an extended version of the standard MSI code that can encode up to 16 digits.


Overall, MSI codes are a reliable and versatile form of product identification and inventory management, and are widely used across many different industries. Whether you’re a logistics provider, manufacturer, or distributor, using MSI codes can help you improve efficiency, reduce costs, and gain valuable insights into your business operations.
