Google Pay

适用于：支持Google Pay支付场景

该支付方式是由Google Pay拉起支付，需集成在商户客户端，消费者在商家客户端完成支付。

1. 它如何工作？

Google Pay 使用特定设备的标记化信用卡或借记卡凭证 (DPAN) 代替支付账号 (PAN)。当客户使用 Face ID、Touch ID 或密码确认支付时，标记化的卡数据会返回到您的应用程序或网站。然后，该令牌就可以传递给您的支付服务提供商（PSP），像处理一般的在线信用卡或借记卡支付一样进行处理。

目前任何常规的借记卡或信用卡交易都可以使用 Google Pay。Google Pay 适用于所有主流PC或移动网络浏览器。

2. Google Pay集成

您可以在App或网页内集成Google Pay，并且需要实施 Google API 才能启动 Google Pay 交易。

与 Google Pay 集成后，Google会创建一个 token，请把paymentData.paymentMethodData.tokenizationData.token做base64_encode后传递给YabandPay，其字段为 payment_token_object，以便解密和处理。
