What is MSI Plessey used for?
MSI, also called Modified Plessey, is a numeric-only symbology built for shelf-edge labels and warehouse inventory tags. It is variable length and continuous, and it is still used for supermarket shelf tagging and internal stock control in retail back offices.
MSI is not intended for point-of-sale scanning and carries no product identity beyond whatever number you assign it. Choose it for internal numeric references where the scanning hardware is already configured for MSI; otherwise Code 128 encodes the same data more compactly.
- Supermarket shelf-edge labels
- Warehouse inventory tags
- Internal stock control references
