Itf 14, also known as EAN/UCC-14, is the GS1 implementation
of an Interleaved 2 of 5 bar code to encode a Global Trade Item
Number. ITF-14 symbols are generally used on packaging levels of a
product. The ITF-14 will always encode 14 digits.
Encoding
Itf 14 encodes pairs of digits; the first digit is encoded in the
five bars ("black lines"), while the second digit is encoded in the
five spaces interleaved with them ("white lines"). Two out of every
five bars or spaces are wide (hence 2 of 5).
Check Sum
ezBarcodeComponent automatically add a Mod 10 check digit.
Itf 14 Character Set
The symbology of the Itf 14 character set consists of the numbers
0-9.
