/**
 * Java&#x2122; Smart Card I/O API.
 *
 * This specification describes the Java Smart Card I/O API defined by
 * <a href="http://jcp.org/en/jsr/detail?id=268">JSR 268</a>.
 *
 * It defines a Java API for communication with Smart Cards
 * using ISO/IEC 7816-4 APDUs. It thereby allows Java applications to interact with
 * applications running on the Smart Card, to store and retrieve data
 * on the card, etc.
 *
 * <p>
 * The API is defined by classes in the package
 * {@code javax.smartcardio}. They can be classified as follows:
 *
 * <dl>
 * <dt>Classes describing the corresponding Smart Card structures
 * <dd>
 * <a href="ATR.html">ATR</a>,
 * <a href="CommandAPDU.html">CommandAPDU</a>,
 * <a href="ResponseAPDU.html">ResponseAPDU</a>
 *
 * <dt>Factory to obtain implementations
 * <dd>
 * <a href="TerminalFactory.html">TerminalFactory</a>
 *
 * <dt>Main classes for card and terminal functions
 * <dd>
 * <a href="CardTerminals.html">CardTerminals</a>,
 * <a href="CardTerminal.html">CardTerminal</a>,
 * <a href="Card.html">Card</a>,
 * <a href="CardChannel.html">CardChannel</a>
 *
 * <dt>Supporting permission and exception classes
 * <dd>
 * <a href="CardPermission.html">CardPermission</a>,
 * <a href="CardException.html">CardException</a>,
 * <a href="CardNotPresentException.html">CardNotPresentException</a>
 *
 * <dt>Service provider interface, not accessed directly by applications
 * <dd>
 * <a href="TerminalFactorySpi.html">TerminalFactorySpi</a>
 *
 * </dl>
 *
 *
 * <h2>API Example</h2>
 *
 * 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>
