MSI Plessey - Barcode Type¶
The original Plessey barcode was developed for the library industry, though today the MSI Plessey code is typically used for inventory management in retail environments.
Based on Plessey and developed by MSE Data Corporation, MSI Plessey is available with a range of check digit options by setting option_2 or by using the --ver= switch. Any length numeric (digits 0-9) input can be encoded. The table below shows the options available:

| 1 | Modulo-10 |
| 2 | Modulo-10 & Modulo-10 |
