MSI, Plessey.
Plessey code supports numerals 0-9, plus six additional characters (typically A-F). Plessey uses a check digit, but the check digit may be calculated several different ways. To allow the user some flexibility, Cognitive printers do not calculate or print the check digit. You must calculate and enter the check digit manually, according to the requirements of your bar code system.
MSI is a modified Plessey code that uses two check digits. Cognitive printers automatically calculate and add the check digits to the bar code. Check digits are not printed in the human-readable bar code subtext.
