title: External fingerprint integration with android device
body: <p>I'm developing an APP for android devices and I'm needing to authenticate the employees with their fingerprint. I have some questions to help me develop it in the best way.</p>
  
  <ol>
  <li>Is there an android device with integrated fingerprint scanner and you can retrieve the info of the image template?</li>
  <li>Is there an external scanner which can be used as an external hardware on my app, USB or Bluetooth?</li>
  <li>Do the devices offer a android SDK, or an API for integration with my App.</li>
  </ol>
  
  <p>Thanks all.</p>
