Java Codabar - Introduction


It is also known as Codeabar, Ames Code, NW-7, Monarch, Code 2 of 7, Rationalized Codabar, ANSI/AIM BC3-1995 or USD-4.

Codabar is a linear barcode symbology developed in 1972 by Pitney Bowes Corp. It was designed to be accurately read even when printed on dot-matrix printers for multi-part forms such as FedEx airbills and blood bank forms, where variants are still in use as of 2007.
This symbology is used by U.S. blood banks, photo labs, and on FedEx airbills. Because Codabar is self-checking, it does not define a check digit. This symbology starts and finishes with one of four possible characters A, B, C, or D.
