What is a Codabar?
Codabar is a self-checking barcode that is designed to be read on printed forms, especially from dot-matrix printers. Its typical uses include Fed-Ex packages and blood bank forms. In many ways, the Codabar code has become outdated, as newer code forms now allow a much larger amount of information to be contained in a much smaller space. However, the Codabar is not yet obsolete and is still in use in libraries (on the spines of books) and several other organizations.
Developed by Pitney Bowes, Inc. in 1972, Codabar is also referred to as the self-checking barcode. It is a discrete symbol that encodes up to 16 different characters along with 4 start/stop characters.
Codabar can encode digits from zero to nine with six symbols (-:.$/+), and lastly, the start/stop characters - A, B, C, D, E, *, N, or T. The start/stop characters should not appear elsewhere in the barcode and should be used in matching pairs. Also, there is no established checksum digit for Codabar as it is self-checking.

As compared to the newer symbologies that can hold more data information in a lesser area, the Codabar barcodes have a bigger installed base in libraries.
Where is a Codabar used?
