The Interleaved 2 of 5 (or ITF) code was developed from an earlier symbology called simply Code 2 of 5. Code 2 of 5 is numeric and has bars which can be wide or narrow. Spaces carried no information, and therefore their width was not critical.
The Interleaved 2 of 5 symbology was suggested as a way of shortening the length of the code by using the spaces to carry information. Data is encoded in pairs of digits with the bars representing the first character of a pair and the spaces representing the second character.
