Interleaved 2 of 5 is
a numeric-only barcode widely used in warehouse and industrial applications. The data must
consist of an even number of digits.
Each data character is composed of 5 elements, either 5 bars or 5 spaces. Of these 5
elements, two are wide and three are narrow. Adjacent characters are interleaved,
alternating the spaces from one character with the bars of the other.
Note on the "Code 25" name":
Interleaved 2 of 5 is sometimes referred to as Code 25. This is not a precise term, as
Code 25 is also sometimes used to mean Standard 2 of 5 or Industrial 2 of 5.
