# About MSI-Plessey barcodes

> Learn what MSI-Plessey numeric barcodes are, where they are still used on store shelves, and why many modern scanners can't read them.

![Example of an MSI-Plessey barcode](https://mintcdn.com/taltech-bdc45607/90dE9DPyCdPJ5zuC/images/barcode-msi-100dpi.png?fit=max\&auto=format\&n=90dE9DPyCdPJ5zuC\&q=85\&s=1d3df2be0857c0e693af025cf845c86e)

MSI-PLESSEY is a variable length, numeric-only symbology that is based on a four-bit binary number scheme. One of the earliest barcode symbologies ever developed, each symbol is framed by a start and stop pattern and contains a check character that is calculated from the values of each of the encoded data digits. However, MSI-Plessey is rarely used in anything other than grocery store shelf-marking applications. In fact, most modern barcode readers do not provide support for reading MSI-Plessey symbols.
