title: External fingerprint scanner for non-rooted Android tablets
body: <p>We want to develop an application where users will be using a handheld scanner for taking fingerprint of the customer via an android tablet. Now, I have a few questions:</p>
  
  <ol>
  <li>I went through many discussions here as well as on other forums, but
  nobody really mentioned the status of the device, ie. Rooted or
  stock. Now does a non-rooted android tablet device support third
  party scanners?  </li>
  <li>I read somewhere that the device needs to have UVC
  kernel. Is this necessary? Or will any device with OTG support work?</li>
  <li>Found a tablet from a french mobile security company, tablet named
  Tazpad. It provides an in-built biometric. Does anybody have any
  experience with it? </li>
  <li>Is bluetooth scanner a possible option?</li>
  </ol>
  
  <p>Please note that this will be for a banking organization and we cannot play with the kernel of the device. They are already opting to use Samsung Galaxy Tab 10.1. But if this device does not support, then we can suggest any other tablet. </p>
  
  <p>Thanks</p>
