Barcode length
Barcode length (number of characters) for Interleaved 2 of 5 = [barcode data + check digit if
applicable]. The minimum length possible is 2 characters.
Interleaved 2 of 5 always encodes an even number of characters. To handle codes with an
odd number of characters, the ScanPlus will accept a code with the last character printed
as 5 narrow bars. In this case, all useful characters are transmitted.
