laravel cashier - save creditcard last 4 number and expire date

I'm using laravel 5.2 with cashier package this is the form that i'm using in order to get the client creditcard token:

<form action="/your-server-side-code" method="POST">
  <script
    src="http://ift.tt/1doUtf9" class="stripe-button"
    data-key="test_token"
    data-amount="999"
    data-name="Demo Site"
    data-description="Widget"
    data-image="http://ift.tt/1HOsSjY"
    data-locale="auto">
  </script>
</form>

after it the form is submitted automatically And i get the regular answer from the server that contain the client token.

How i can save the credit-card last 4 number and expire date that the user enter?

Thank!
