#Quick Start

// It's an example of reading a TWN Health Insurance Card
CommandAPDU cmd1 = APDU.builder().setINS(INS.SELECT_FILE).setP1((byte) 0x04)
                                 .setData("D1580000010000000000000000001100").build(); // Lc field is set automatically by given data length
CommandAPDU cmd2 = APDU.builder().setINS(INS.GET_DATA).setP1((byte) 0x11)
                                 .setData((byte) 0x00, (byte) 0x00).build();          // It's fine to use a byte array to set the data

ListMultimap<CardTerminal, ResponseAPDU> res // Each value stores all ResponseAPDUs of a CardTerminal
    = CardReader.getInstance().read(cmd1, cmd2);

#Feature Automated reader. It performs a task by a time interval if there is any change(card switching, ...) happened on the responses from card terminals.

AutomatedReader reader = new AutomatedReader(cmd1, cmd2);
reader.reading(1000, new CardTask() { // It reads from all CardChannels every second(1000ms)

    public void execute(CardTerminal terminal, List<ResponseAPDU> responses) {
        ...
    }

});

...

reader.stop();
