You have to do XHR request to server along with tag then retrieve RFID from server and then assign it to javascript variable.

The way you are doing not possible.

Try something like this, use json_encode with Array of data.

<script>
    window.variable = {!! json_encode([
        'variable' => 'value',
    ]) !!};
</script>
