Code39 Extended Barcode

This is an extended version of the Code39 barcode that supports the full ASCII character set. If there is a requirement to use the Code39 barcode with characters other than numbers and uppercase alphabets, then this is the recommended barcode. As this barcode is based on Code39, it is also very simple and easy to use. It is, however, not the most dense in terms of number of characters per inch.

Examples
To encode the data "abcd" without the check digit manually, simply key in "*+A+B+C+D*" and select the FontCode39H3.ttf font. The output is as follows :

To encode the data "abcde" with the check digit manually, simply key in "*+A+B+C+D+E7*" and select the FontCode39H3.ttf font. The output is as follows :

The "7" is the check digit and its computation is illustrated in the section below.

How to compute the check digit

The Code39 barcode uses the Modulo 43 Check Digit computation.

Supported Characters+A+B+C+D+E
Values41104111411241134113
Sum :41 + 10 + 41 + 11 + 41 + 12 + 41 + 13 + 41 + 14 = 265
Modulo 43 :265 % 43 = 7 (which is the character '7')
