Check Digit Output Status (Interleaved 2 of 5)
Usage:
It is has been popular because it is the most dense symbology for printing
numeric characters less than 10 characters in length; however, Microscan
does not recommend this symbology for any new applications because of
inherent problems such as truncation.
Definition:
A dense, continuous, self-checking, numeric symbology. Characters are
paired together so that each character has five elements, two wide and
three narrow, representing numbers 0 through 9, with the bars representing
the first character and the interleaved spaces representing the second
character. (A check digit is highly recommended.)
Important: You must set Symbol Length in order to decode I 2/5 symbols.
