$stripe = new StripeClient('STRIPE_SECRET_KEY');

$cards = $stripe->paymentMethods->all(['customer' => 'CUSTOMER_ID', 'type' => 'card']);

$fingerprints = [];

foreach ($cards as $card) {
   $fingerprint = $card['card']['fingerprint'];

    if (in_array($fingerprint, $fingerprints, true)) {
      $stripe->paymentMethods->detach($card['id']);
   } else {
     $fingerprints[] = $fingerprint;
   }
}
