<p>Usually the application dictates what standard should be followed and there is
|
||
no choice other than following the applicable industry standard. </p>
|
||
<p>However, if the usage is strictly internal it is possible to chose any
|
||
symbology. However for generic usage we would recommends using either Code 39 or
|
||
Code 128 since they offer great flexibility, supports large character sets and
|
||
is fairly efficient in terms of space/datasize ratio.</p>
