[I 2 of 5 Bar Code Sample]

ITF is the symbology often used on outer cases of consumer goods (often in a fixed length 14 digit format). These are sometimes referred to as Case Codes.

Interleaved 2 of 5 is a high density, self checking, continuous numeric barcode. It has mainly been used in the distribution industry.

Every Interleaved 2 of 5 character actually encodes two digits, one in bars and the other in spaces. The complete Interleaved 2 of 5 symbol consists of the Start Code, the data and the stop code.

Interleaved 2 of 5 is often used with a Modulo 10 check digit to improve data security, the total number of digits used in Interleaved 2 of 5 must be even, if a message has to be encoded with an odd length, the addition of a zero to the data is used.

A popular numeric only code, used mainly for industrial applications. The principal feature of ITF is that each element of the code actually encodes two digits - hence the code is quite compact and good for encoding longer sequences of digits. Two main drawbacks however are that there is no inbuilt security and the structure of the code means that it’s sometimes possible to get partial reads. For these reasons it’s recommended that some form of checking or fixed length reading be implemented within the application (or intelligent scanner) if using ITF. So called “bearer bars” bars running along the top and bottom of the code are sometimes also added to help prevent misreads. The only other real limitation is that ITF must always encode an even number of digits, the convention being to add leading zeros to odd digit lengths.
