/**
 * A permission for Smart Card operations. A CardPermission consists of the
 * name of the card terminal the permission applies to and a set of actions
 * that are valid for that terminal.
 *
 * <p>A CardPermission with a name of <code>*</code> applies to all
 * card terminals. The actions string is a comma separated list of the actions
 * listed below, or <code>*</code> to signify "all actions."
 *
 * <p>Individual actions are:
 * <dl>
 * <dt>connect
 * <dd>connect to a card using
 * {@linkplain CardTerminal#connect CardTerminal.connect()}
 *
 * <dt>reset
 * <dd>reset the card using {@linkplain Card#disconnect Card.disconnect(true)}
 *
 * <dt>exclusive
 * <dd>establish exclusive access to a card using
 * {@linkplain Card#beginExclusive} and {@linkplain Card#endExclusive
 * endExclusive()}
 *
 * <dt>transmitControl
 * <dd>transmit a control command using
 * {@linkplain Card#transmitControlCommand Card.transmitControlCommand()}
 *
 * <dt>getBasicChannel
 * <dd>obtain the basic logical channel using
 * {@linkplain Card#getBasicChannel}
 *
 * <dt>openLogicalChannel
 * <dd>open a new logical channel using
 * {@linkplain Card#openLogicalChannel}
