Start/Stop Code

The start/stop code is a unique character identifying the leading and trailing end of the bar code. The start/stop code is automatically produced with each bar code. The start/stop code structure permits bidirectional bar code scanning.

Data Field

The bar code symbol uses a nine-position bar/no-bar pattern of tall (full) bars of uniform height. Use the letters “A,” “B,” “C,” or “D” to specify the type of FIM.

Figure 14 illustrates how to generate a horizontal FIMC bar code and a

POSTNET bar code.
