MSI Data Corporation's barcode; originally based on the 'Plessey' barcode and also known as Modified Plessey. Only digits 0-9 can be encoded.

Black bars and white bars are used in two widths: the wide bars are twice the width of the narrow bars.

The format does not require the barcode to be of a fixed length, but some organizations may standardize their bar-codes to be of a specified length.
