如果你不想使用NXP库TapLinx进行构建，可以考虑使用其他RFID库来实现相关功能。以下是一个示例，使用Java的RFID库jSerialComm：

import com.fazecast.jSerialComm.SerialPort;
import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;

public class RFIDReader {
    private SerialPort serialPort;
    private InputStream input;
    private OutputStream output;

    public RFIDReader(String portName) {
        serialPort = SerialPort.getCommPort(portName);
        serialPort.setBaudRate(9600);
        serialPort.setComPortTimeouts(SerialPort.TIMEOUT_READ_BLOCKING, 0, 0);
    }

    public void open() throws IOException {
        if (serialPort.openPort()) {
            input = serialPort.getInputStream();
            output = serialPort.getOutputStream();
            System.out.println("Port opened successfully.");
        } else {
            throw new IOException("Failed to open port.");
        }
    }

    public void close() {
        serialPort.closePort();
        System.out.println("Port closed.");
    }

    public String readTag() throws IOException {
        byte[] buffer = new byte[1024];
        int bytesRead = input.read(buffer);
        return new String(buffer, 0, bytesRead);
    }

    public void writeTag(String tag) throws IOException {
        output.write(tag.getBytes());
        output.flush();
    }

    public static void main(String[] args) {
        RFIDReader reader = new RFIDReader("COM1");
        try {
            reader.open();
            String tag = reader.readTag();
            System.out.println("Read tag: " + tag);
            reader.writeTag("new tag");
            System.out.println("Tag written successfully.");
        } catch (IOException e) {
            e.printStackTrace();
        } finally {
            reader.close();
        }
    }
}

请注意，此示例假设使用串行端口（例如COM1）连接RFID读写器。你需要根据实际情况更改端口名。此外，该示例只是一个简单的框架，你需要根据你的具体需求进行适当修改和扩展。
