离线使用 Shopify POS
Shopify POS 需要 Internet 连接才可与 Shopify 后台同步、通过电子邮件发送收据以及收取卡付款。可以通过 Wi-Fi 网络或蜂窝数据建立 Internet 连接。
如果您断开了 Internet 连接或者您要在不访问 Internet 的情况下在快闪店进行销售，您仍能够处理部分类型的交易。本指南介绍了哪些功能和硬件需要 Internet 连接，以及处于离线状态后如何同步您的 Shopify POS 和后台。
需要 Internet 连接的功能
以下 Shopify POS 功能需要 Internet 连接。

| 登录 | Shopify POS 应用需要 Internet 连接才能在您登录时导入您商店的产品。如果您在登录后断开了 Internet 连接，那么只要您不注销，就可以继续使用该应用。 |
| 创建新产品 | 您无法在没有 Internet 连接的情况下保存新产品。 |
| 将 Shopify POS 与 Shopify 后台同步 | 当您离线时，Shopify POS 无法与您的 Shopify 后台同步订单和库存。当您在离线后重新连接至 Internet 时，您的订单和库存应会自动同步。您还可以手动强制 Shopify POS 应用与您的 Shopify 后台同步。 |
| 处理卡交易 | 如果您没有 Internet 连接，则无法处理信用卡、借记卡或礼品卡交易，但您仍可以接受现金或自定义付款方式。 |
| 按照订单为客户发货 | 如果您没有 Internet 连接，则无法完成为客户发货的订单。 |

Using Shopify POS offline
Shopify POS needs an internet connection to sync with your Shopify admin, send receipts by email, and take card payments. The internet connection can be made using a wi-fi network or cellular data.
If you lose your internet connection or you're going to be selling from a pop-up location without internet access, then you can process some types of transactions. This guide explains which features and hardware require an internet connection, and how to sync your Shopify POS and admin after being offline.
Functionality that requires an internet connection
The following Shopify POS functionality requires an internet connection.
Function Details Logging in The Shopify POS app requires an internet connection to import your store's products when you log in. If you lose your internet connection after logging in, then you can continue using the app as long as you don't log out. Creating new products You can't save a new product without an internet connection. Syncing Shopify POS with your Shopify admin Shopify POS can't sync orders and inventory with your Shopify admin while you're offline. When you reconnect to the internet after being offline, your orders and inventory should sync automatically. You can also manually force the Shopify POS app to sync with your Shopify admin. Processing card transactions If you don't have an internet connection, then you can't process credit, debit, or gift card transactions, but you can still accept payments by cash and custom payment methods.

From the Orders screen, swipe the orders list down to refresh it. Your Shopify admin and POS syncs their orders and inventory.
