Code 128 barcode check digit default

Posted on 2012-08-20
Last Modified: 2012-08-20
I am programming an automatic check digit calculator for a barcode app, and I'm unsure which value to use for the check digit if the modulo 103 function returns a zero.  Any help is appreciated.  For instance, the value "0B09C2" calculates to a value of 618.  Mod 103 of 618 is 0.  Which ascii character should I display?

    The ASCII character to apply for a zero depends on what font you are using. Each font vendor uses different locations. For example, refer to
    and with this font, the ASCII value is 194, and if you using a font from Azalea, the ASCII value is 206. In any case, it is better to get your font from a vendor (such as IDAutomation or Azalea) that already has the source code written for you, so you don't have to write it from scratch.
