BCT_CODABAR
Field of Application
Codabar is a universal barcode with many applications in the industry. It is particularly used in the field of medical applications.
In Japan this code is also known as NW-7
Charset / Number of Characters
The charset comprises the digits 0..9 and the symbols minus, dollar sign, colon, slash, period and plus. The number of characters is not limited.
Codabar supports four different start / stop characters: A, B, C, D. Each code must begin and end with A, B, C or D. These characters may no be used within the barcode itself.
Checkdigit
The use of a checkdigit is optional. The barcode library can generate it automatically.
Characteristics
•The aspect ratio between thin and thick modules can be adjusted using the properties BarcodeThinBar and BarcodeThickBar. To adjust for example a ratio of 1 : 2,5 set BarcodeThinBar = 2 and BarcodeThickBar = 5.
•Codabar does not code all characters in the same width. The special characters ":", "$", "/", "." and "+" require one module more than the digits 0..9 and the "-" sign. Therefore your applications need to reserve enough space.
