title: Programming with RFID scanners + Java?
body: <p>I'm attempting to build a simple authentication system built around RFID. Basically I have an old computer and I'd like to buy a USB RFID scanner. However, I have no experience in this area and so I'm unsure what I'd be looking to buy.</p>
  
  <p>Basically I'm looking for something that hopefully comes with an API of some sorts that allows me to log users in with RFID cards. Could anyone recommend me a good device / resource for accomplishing this? </p>
