Quiet Zone
Both ends of the bar code structure have blank quiet zones. The quiet zones
should be at least 0.25 inches wide and completely blank to ensure accurate
reading of the start/stop codes and to prevent adjacent bar codes from
overlapping. You are responsible for providing sufficient space on the form for
the quiet zones.

Start/Stop Codes
Unique start and stop codes permit bidirectional scanning. Both start and stop
codes contain bars and spaces. They are automatically produced.

Data Field
The bar code symbol uses a series of wide and narrow bars and spaces to
represent numeric characters. The structure is 2 wide elements (bars or
spaces) and 3 narrow elements. In the bar code, two characters are
interleaved (paired); bars are used to represent data characters occupying
the odd-numbered positions, and spaces are used to represent data
characters occupying the even-numbered positions.

Readable Data
The optional readable data field provides a readable interpretation of the bar
code data. Bar code data is printed below the horizontal bar code symbol and
to the left of a vertical bar code symbol. The lower guard band is provided
when the readable data field is selected.
