<h4>Design Restrictions</h4>
|
|
<ul>
|
|
<li>Must be printable to 8x8mm curved area</li>
|
|
<li>Must be readable by a regular phone</li>
|
|
</ul>
|
|
|
|
<h4>Benefits</h4>
|
|
<ul>
|
|
<li>Streamline text input</li>
|
|
<li>Trace Vial to shot</li>
|
|
<li>Easy to track counterfeiters</li>
|
|
</ul>
