The Msi barcode developed by the MSI Data Corporation. It is based on the original Plessey symbology. Sometimes the Msi barcode is called the Modified Plessey. The basic implementation of the Msi barcode is used for warehouse shelves and inventory.

Msi is a variable length, numeric-only symbology and allows to output digits 0..9. One or two check digits calculated by modulo-10 or modulo-11 can be used. Each character of the barcode consist of 4 elements. If the element is the binary 0 then the barcode has the 1 module width and a space has 2 modules. If the element is the binary 1 the bar the 2 module width and a space has 1 modules. So, each character has 12 modules length. Therefore, this barcode has very low data density.
A "Msi" barcode. "1234567890" is a number encoded in the barcode.
