# 存档信用卡

想要为客户存储或保留信用卡信息，以便未来扣款？以下介绍如何通过 Sesami 和 Shopify 处理这一点。

## Sesami 的付款运作方式

Sesami 不直接处理付款——付款通过 Shopify 的结账系统完成。Shopify 维护 PCI 合规，这意味着商家不能在 Shopify 后台手动存储信用卡号码。

## 推荐：Downpay

[Downpay](https://apps.shopify.com/downpay) 是一个与 Sesami 配合良好的 Shopify 应用，并提供：

* **卡片留存** 通过 Shopify 的 API
* **定金和部分付款**
* 从订单页面或 POS 收取剩余余额

## 替代方案

* **发送发票** 给客户以收取剩余余额
* **收取定金** 在预约时，并在就诊时收取剩余部分（参见 [订金](/zh-cn/fu-kuan/deposits.md))

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://help.sesami.co/zh-cn/fu-kuan/credit-card-on-file.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
