The MSI Plessey barcode has been designed by the Plessey Company, England in 1971. It has been used in libraries and stores.
The code can display only the number 0-9 and has no fixed length. Today this type of code is outdated and is no longer used. Because of this most barcode scanners can not recognize this type of code.
