<h4>Note Information</h4>

<tr><td>Issuing Authority</td><td><input id="qr-issuer" type="text" placeholder="Federal Reserve"/></td></tr>
<tr><td>Issuing Date</td><td><input id="qr-date" type="text" placeholder="YYYYMMDD"/></td></tr>

<h4>Printing & Distribution Information</h4>

<h4>Design Restrictions</h4>
<ul>
<li>QR must fit a 10x10mm area on a bank note</li>
<li>QR must contain all the fields of the note</li>
<li>Must be readable by a regular phone</li>
</ul>
<h4>Benefits</h4>
<ul>
<li>Counterfeiters can only duplicate notes (changing serial number breaks the signature)</li>
<li>Duplicated serial # are easier to track down</li>
<li>Build a "Revocation List" for individual numbers</li>
</ul>
