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.

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. The lower guard band is provided when the readable data field is selected.

Check Digit

The modulo-10 check digit is automatically calculated and inserted in the bar code symbol. The check digit provides the means to verify accurate scanning.
