Description

The Interleaved 2 of 5 (also called the I 2 of 5 or ITF) is a numeric, fourteen-
character barcode (see figure below). It is typically used in industrial and
master carton labeling. It has start and stop codes allowing it to be read back-
wards and forwards. Interleaving allows the characters to overlap, creating a
higher density barcode than the Code 3 of 9. I2of5 is referred to as a "com-
petitive" code, as the functionality to read this code was added to the DI900/
DI950 scanning so the machine could run jobs initially created for competitors'
machines.
The symbology uses bars to represent the first character and the interleaved
(white) spaces to represent the second character. Each character has two
wide elements and three narrow elements. The figure at left illustrates the In-
terleaved 2 of 5 symbology format for the numbers "3 8 5 2".
The Interleaved 2 of 5 uses combinations of 2 of the 5 bars or spaces to cre-
ate characters. The odd and even numbered characters encoded in the bars
and spaces fit together like a puzzle. Interleaving or interlacing of the bars and
spaces allows for a high-density, compact code. The UPC is a special type of
Interleaved 2 of 5 barcode.
