【问题描述】：

我现在已经为支付选项开发了 iphone 应用程序我无法下定决心，这是最好的 1. PayPal 2. Braintree。

我想在每次使用时保存用户的付款信息。所以只有一次用户必须填写信息，我可以使用下次保存的信息进行付款。就像 UBER 应用做的那样……这可能在移动应用端吗？

【问题讨论】：

是的，有可能。
我建议您更改您的问题，以便您明确表示保存卡和帐单详细信息。保存名称、登录详细信息等是另一个问题的范围这就是该问题被否决的原因

【解决方案1】：

您可以使用 Paypal 来满足您的要求，并且 Paypal 直接不提供任何凭据，或者您必须在填充信息时访问该特定用户的令牌。该令牌由 paypal 提供（只是认为它就像在您的应用中记住我一样）。

注意：我自己没有实现这个，但我认为这一定是方法。

是的，您可以使用 paypal 通过他们的 rest api 来保存卡

以下是来自 api 示例和文档站点的 paypal 代码 http://paypal.github.io/PayPal-PHP-SDK/

// # Create Credit Card Sample
// You can store credit card details securely
// with PayPal. You can then use the returned
// Credit card id to process future payments.
// API used: POST /v1/vault/credit-card


require __DIR__ . '/../bootstrap.php';
use PayPal\Api\CreditCard;

// ### CreditCard
// A resource representing a credit card that is 
// to be stored with PayPal.
$card = new CreditCard();
$card->setType("visa")
    ->setNumber("4917912523797702")
    ->setExpireMonth("11")
    ->setExpireYear("2019")
    ->setCvv2("012")
    ->setFirstName("Joe")
    ->setLastName("Shopper");

// ### Additional Information
// Now you can also store the information that could help you connect
// your users with the stored credit cards.
// All these three fields could be used for storing any information that could help merchant to point the card.
// However, Ideally, MerchantId could be used to categorize stores, apps, websites, etc.
// ExternalCardId could be used for uniquely identifying the card per MerchantId. So, combination of "MerchantId" and "ExternalCardId" should be unique.
// ExternalCustomerId could be userId, user email, etc to group multiple cards per user.
$card->setMerchantId("MyStore1");
$card->setExternalCardId("CardNumber123" . uniqid());
$card->setExternalCustomerId("123123-myUser1@something.com");

// For Sample Purposes Only.
$request = clone $card;

// ### Save card
// Creates the credit card as a resource
// in the PayPal vault. The response contains
// an 'id' that you can use to refer to it
// in future payments.
// (See bootstrap.php for more on `ApiContext`)
try {
    $card->create($apiContext);
} catch (Exception $ex) {
    // NOTE: PLEASE DO NOT USE RESULTPRINTER CLASS IN YOUR ORIGINAL CODE. FOR SAMPLE ONLY
    ResultPrinter::printError("Create Credit Card", "Credit Card", null, $request, $ex);
    exit(1);
}

// NOTE: PLEASE DO NOT USE RESULTPRINTER CLASS IN YOUR ORIGINAL CODE. FOR SAMPLE ONLY
 ResultPrinter::printResult("Create Credit Card", "Credit Card", $card->getId(), $request, $card);

return $card;
