Overview
MSI Modified Plessey is a continuous, non-self-checking, arbitrary length, numeric symbology.
Variants
Plessey (UK) is the original code upon which MSI Modified Plessey was based.
Invoking
- The data can consist of any number of digits.
- The includecheck option calculates the check digit or check digits.
- The includecheckintext option makes the calculated check characters appear in the human readable text.
- The checktype option is used to specify the type of checksum, either:
- checktype=mod10 (default)
- checktype=mod1010
- checktype=mod11
- checktype=ncrmod11
- checktype=mod1110
- checktype=ncrmod1110
- The badmod11 option allows a checktype=mod11 checksum value of 10 to be encoded with a pair of check digits 10. Normally in checktype=mod11, any input whose checksum evaluates to 10 is considered invalid having no correct representation.
