  <p>The code is:</p>
  
  <pre><code>        TerminalFactory terminalFactory;
          terminalFactory = TerminalFactory.getDefault();
          System.out.println(terminalFactory);
  
  
          List&lt;CardTerminal&gt; terminals = terminalFactory.terminals().list();
          System.out.println("Terminals: " + terminals);
          if (terminals.isEmpty()) {
  
              throw new Exception("No card terminals available");
  
          }
  </code></pre>
  
  <p>Its strange because the RPi recognize the card reader with the command "lsusb" where appear "Bus 001 Device 007: ID 072f:2200 Advanced Card Systems, Ltd".</p>
  
  <p>I have been reading days ago and people talk about install the PC/SC Package from the page of ACR122U - <a href="http://www.acs.com.hk/en/products/3/acr122u-usb-nfc-reader/" rel="nofollow">http://www.acs.com.hk/en/products/3/acr122u-usb-nfc-reader/</a> - and it will solve the problem. Indeed, that package is useful to the amd64 and i386 architecture and the RPi has a ARM architecture  with Raspbian (Debian/Linux). </p>
  
  <p>My question is, could you help me in the way to install that package in a ARM architecture? or someway to solve my problem?</p>
  
  <p>Thank you</p>
