You might want to display additional

you can track your products or spot problems.
This section describes how to manage the
data transmission of your bar code.
3.1.1 Character length
It shows the number of the character length
at the beginning of a bar code. For example, if
your bar code is “Argox,” the result is
“0005Argox.” The maximum character length
of the bar code varies between bar code
types. If the number is smaller than 1000, it
pads the number with leading zeros.
