USER'S GUIDE
CODABAR
Codabar is a primarily numeric, self-checking and variable-length bar code for
up to 16 data characters. There is a leading and trailing quiet zone and a start and
stop character (A B C D).
This standard is used primarily for numeric applications; you can encode the
digits and six special characters (- . $ / + :).
The digits and the $ and - symbol are printed with one wide bar and one space.
The start and stop characters (A, B, C and D) are printed with one wide bar and
two white spaces.

Bar height: 0.3", narrow bar width: 12 mils, narrow to wide ratio: 2.5

UPC-A
UPC-A is a fixed-length, numeric bar code that allows to encode 12 charac-
ters.
The bar codes are composed of a number system digit (encoded in odd par-
ity), the manufacturer’s code (encoded in odd parity), the product code and a
check digit. (The user encodes 11 digits.)
