As discussed biometric support is enabled by effectively emulating a USB card reader. The biometric device is connected via USB to an MFD running PaperCut embedded and also connected to the network via a LAN port. The typical workflow of the various biometric solutions is:
<ul>
 	<li>The user scans their fingerprint at the biometric scanner connected to the MFD</li>
 	<li>The fingerprint information is sent via the network to the biometric software running on a server</li>
 	<li>The fingerprint is then looked up in a biometric database and verified as a user on the network</li>
 	<li>Verified users have a unique number associated with their account</li>
 	<li>This unique ID number is sent through the network back to the bioscanner</li>
 	<li>The bioscanner sends the unique ID number via a USB connection to the MFD. This works just like a USB card reader scanning a card</li>
 	<li>The unique ID number matches the Card/ID number of a user in PaperCut</li>
 	<li>The user is logged into the embedded software</li>
 	<li>The time it takes to perform all these actions is barely noticeable</li>
</ul>
