The individual characters are separated by a gap that is the width of a narrow element. Usually the code 39/3 of 9 with a "*" at the beginning and at the end of the code is used as a start and stop character. Furthermore, a check digit can be appended to improve security. This check digit is calculated with Modula10.

Code 39/3 of 9 FullAscii
Character set: All 128 characters of the "simple" ASCII table.
The characters have the same structure as with "Regular Code39 / 3 of 9", only that "toggles" are used in front of the characters. An "a" is achieved, for example, by placing a "+" in front of an "A" in the code. The correspondingly configured reader will then interpret the string “+ A” as “a”.
