QuestionHow to Read and Write to RFID(v9t557) as Human Interface Device C# Pin

Am trying to read/write to card using RFID reader, but the RFID reader is appearing under Human Interface Device, so far I have been able to get all Human Interface Devices into a DropDownlist using HidLibrary here is my code

HidDevice[] mahdDevices;
    private void Form1_Load(object sender, EventArgs e)
    {
        mahdDevices = HidDevices.Enumerate().ToArray();
        
        for (int i = 0; i < mahdDevices.Length; i++)
        {
            cmbDevices.Items.Add(mahdDevices[i].Description);
        }
    }

But now am not sure of how to send and receive data from the HID selected on the drop downlist, I also checked Hardware IDs of RFID device in properties, No idea on what to do with the IDs or how to communicate with HID devices to scan card, this is how i usually communicate with devices using serial port:

_port = new SerialPort();
        _port.PortName = comboBox2.Text;
        _port.BaudRate = 9600;
        _port.Parity = Parity.None;
        _port.DataBits = 8;
        _port.StopBits = StopBits.One;

        if (_port.IsOpen)
        {
            textBox1.Clear();
        }
        else
        {
            _port.Close();
        }
        _port.DataReceived += new SerialDataReceivedEventHandler(RFID_DataReceiver);

Please I need help communicating with HIDs.
