Examples of javax.smartcardio.CardChannel

javax.smartcardio.CardChannel
A logical channel connection to a Smart Card. It is used to exchange APDUs with a Smart Card. A CardChannel object can be obtained by calling the method {@linkplain Card#getBasicChannel} or {@linkplain Card#openLogicalChannel}. @see Card @see CommandAPDU @see ResponseAPDU @since 1.6 @author Andreas Sterbenz @author JSR 268 Expert Group
