8 • Scanning
NOTE: A HCSF is required to scan barcodes in "picket" orientation. "Picket" ori-
entation uses a moving beam scanner. Only one moving beam scanner is present
on a single HCSF. 2D can be read out of the HCSF and remove the limitation of
one moving beam scanner
Code 3 of 9 Barcode
Code 3 of 9 is an alphanumeric barcode. Each character is represented by
five bars and four spaces, making a total of nine elements. Of these nine
elements, three are wide and six are narrow. The space between charac-
ters is called the intercharacter gap. An asterisk is used as a start code and
a stop code indicating where the data starts and ends. The start and stop
codes allow the symbology to be read backwards and forwards.

uses Code 3 of 9 barcodes only.
Interleaved 2 of 5 Barcode
The Interleaved 2 of 5 (also called the I2of5 or ITF) is a numeric barcode.
Start and stop characters are not required. Interleaving allows the charac-
ters to overlap, creating a higher density barcode than the Code 3 of 9. 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 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.
2D Data Matrix Barcodes
Data Matrix 2D barcodes provide a compact barcode option to customers
who would like to keep physical size of the barcode to a minimum making it
easier to fit a barcode into a document.
A key advantage to the Data Matrix barcode over the standard linear bar-
codes (such as Code 3 or 9) is that Data Matrix barcodes can store a larger
amount of data in a smaller sized barcode.
