Remarks
Codabar is a linear symbology, developed in 1972 by Pitney Bowes, Inc. It is most commonly used by libraries, blood banks, and on FedEx airbills.
This symbology can encode 16 characters (0 through 9, and -$:/.+), along with 4 start/stop characters.
Each encoded value must start and stop with A, B, C, or D.
The AreStartStopCharactersVisible property determines whether these start/stop characters are included
in the DisplayValue.
This symbology is self-checking, so no checksum or check digit is required.
For detailed documentation on this symbology's features and how to use them, please see the Codabar documentation topic.
