<p>In the following section we will describe the requirements to encode in each of

the supported symbologies. Some symbologies have strict standard for the data to be

encoded. Trying to encode illegal (or not supported data) will result in a "Data

<p>UPC A = Universal Product Code Version A. </p>
|
|||
|
|
<p>UPC A encodes 12 numeric digits. The first digit identifies the number system
|
|||
|
|
used. The next group of 5 digits identifies the manufacturer. This number is
|
|||
|
|
assigned by the Uniform Code Council (<code class="uri"><a class="uri" href="http://www.uc-council.org" target="_top">UCC</a></code>). The next 5 digits
|
|||
|
|
identify the particular product and are assigned by the manufacturer. The final
|
|||
|
|
digit is a check digit.</p>

<p>The name comes from the that each data character is composed of 5 elements,

|

either 5 bars or 5 spaces. Two elements are 3 modules wide and three elements
|

have a width of 1 module. Adjacent characters are interleaved, mixing the spaces

from one character with the bars of the other.</p>

are 2 modules wide and the rest one module wide. Code 39 is defined in <span class="italic">American National Standards Institute</span> (ANSI)
