I'm building this electron application and I'm trying to integrate RFID to read/write on any tag of any frequencies. I've search the internet for weeks now but nothing works in all I've seen. I have a rfid card reader and card to test with but no head way yet. Help out guys.

var llrp = require("llrp");

const { app, BrowserWindow } = require("electron");

let win;

function createWindow() {
  win = new BrowserWindow({
    width: 800,
    height: 600,
    webPreferences: {
      nodeIntegration: true,
      contextIsolation: false,
    },
  });

  win.loadFile("index.html");

  win.webContents.openDevTools();
  win.on("closed", () => {
    win = null;
  });
}

app.on("ready", createWindow);

app.on("window-all-closed", () => {
  if (process.platform !== "darwin") {
    app.quit();
  }
});

app.on("activate", () => {
    createWindow();
  }
});

var reader = new llrp({
  ipaddress: "192.168.1.102",
  port: 3000,
});

reader.connect();

reader.on("timeout", function () {
  console.log("timeout in session");
});

reader.on("disconnect", function () {
  console.log("disconnect");
});

reader.on("error", function (error) {
  console.log("error: " + JSON.stringify(error));
});

reader.on("didSeeTag", function (tag) {
  console.log("TAG: " + tag.tagID);
});
