6033N/A<h2>Java&#x2122; Smart Card I/O API</h2>
6033N/A
6033N/AThis specification describes the Java Smart Card I/O API defined by
6033N/A<a href="http://jcp.org/en/jsr/detail?id=268">JSR 268</a>.
6033N/A
6033N/AIt defines a Java API for communication with Smart Cards
6033N/Ausing ISO/IEC 7816-4 APDUs. It thereby allows Java applications to interact with
6033N/Aapplications running on the Smart Card, to store and retrieve data
6033N/Aon the card, etc.
6033N/A
6033N/A<p>
6033N/AThe API is defined by classes in the package
6033N/A<code>javax.smartcardio</code>. They can be classified as follows:
6033N/A

6033N/A<dt>Classes describing the corresponding Smart Card structures

</dl>


<h3>API Example</h3>

A simple example of using the API is:
<pre>
    // show the list of available terminals
    TerminalFactory factory = TerminalFactory.getDefault();
    List&lt;CardTerminal&gt; terminals = factory.terminals().list();
    System.out.println("Terminals: " + terminals);
    // get the first terminal
    CardTerminal terminal = terminals.get(0);
    // establish a connection with the card
    Card card = terminal.connect("T=0");
    System.out.println("card: " + card);
    CardChannel channel = card.getBasicChannel();
    ResponseAPDU r = channel.transmit(new CommandAPDU(c1));
    System.out.println("response: " + toString(r.getBytes()));
    // disconnect
    card.disconnect(false);
</pre>
