如何在Java中将RFID标签数据（Askii）转换为字符串

我正在使用Ridberry Pi读取（id12创新）RFID。使用PI4J Java库及其串行示例，我能够读取一些数据，例如（5002CF13C6），我不确定该数据是什么！它假定获得此号码（0002948115）。

这是我的代码：

// create an instance of the serial communications class
final Serial serial = SerialFactory.createInstance();

// create and register the serial data listener
serial.addListener(new SerialDataListener() {
@Override
public void dataReceived(SerialDataEvent event) {
    //-----------
    System.out.print("\n" + event.getData());
    //-----------
}

});

try {
    // open the default serial port provided on the GPIO header
    serial.open("/dev/ttyAMA0", 9600);

    // continuous loop to keep the program running until the user terminates the program
    for (;;) {
        try {

        } catch (IllegalStateException ex) {
            ex.printStackTrace();
        }
        try {
            // wait 1 second before continuing
            Thread.sleep(1000);
        } catch (InterruptedException ex) {
            Logger.getLogger(Rfid.class.getName()).log(Level.SEVERE, null, ex);
        }
    }

} catch (SerialPortException ex) {
    System.out.println("e: RFID setup failed : " + ex.getMessage());
}

为了能够读取真实数据，我应该对event.getData（）做什么？
