MSI was developed by the MSI Data Corporation, based on the original Plessey Code. MSI, also known as Modified Plessey, is used primarily to mark retail shelves for inventory control.

MSI is a continuous, non-self-checking symbology. While an MSI bar code can be of any length, a given application usually implements a fixed-length code.

The following property is specific to the MSI type and available in the Properties panel under the Symbology property:

  • MSI Checksum
    Specifies the bar code’s checksum type, which defines the appearance of checksum bars added to the bar code.
