Manual - Code 39 Extended

Introduction

Code 39 Extended version allows you to write all the ASCII characters from 0 to 127 thanks to the special characters provided by the Code 39. These characters are "$/+%". Since the extended version of Code 39 is optional, you have to check your reader to see if it supports Code 39 Extended. Otherwise, the decoded code will be different from your input.

This class inherits the BakeryCode39 class.
