刷卡器（闪点）的购买地点
加拿大的 Shopify 硬件商店提供刷卡器（闪点）。
安装刷卡器（闪点）
要安装刷卡器，请将闪点连接器连接到 iPad 或 iPhone。您可以使用读卡器附带的塑料适配器以确保安全。
要在使用读卡器时为 iPhone 或 iPad 充电，请将随附的微型 USB 线缆连接到读卡器的直通微型 USB 端口。
如何刷卡
持卡时让卡的磁条面朝下，然后将它刷过读卡器：
问题排查
如果您的读卡器无法使用，请按照以下步骤来测试一笔金额为 1.00 的快速销售产品订单（您可以稍后对订单进行退款）。
步骤：
检查您是否有 Internet 连接。Shopify POS 需要通过 Wi-Fi 或您设备的蜂窝数据连接到 Internet，然后才能处理付款。如果您无法连接到 Internet，那么您将无法处理卡付款。
您是否正在使用兼容的支付服务提供商和货币？只有在下列情况下，您才能使用闪点刷卡器：
- 您的商店位于美国或加拿大 - 您正在使用兼容的支付服务提供商 - 您商店的货币是美元或加元。
如果您不满足以上任一要求，则需要使用受支持的读卡器来收取信用卡付款。
确保您在付款屏幕上点击了信用卡。外部终端支付选项仅在您使用外部支付终端而非 Shopify 支持的读卡器的情况下适用。
检查读卡器是否已正确插入 POS 设备，并确保设备的外壳未挡住读卡器。
请务必正确刷卡，将卡的磁条面背向您。
在付款屏幕上点击信用卡后，拔下读卡器，然后再次将其插入 POS 设备。检查是否显示了已连接读卡器通知。
尝试手动输入信用卡信息。如果可以输入，则表示读卡器有问题。
如果手动输入不起作用，请强制退出 Shopify POS 应用，关闭设备，并拔掉读卡器。重新打开设备，打开 Shopify POS，插入读卡器并尝试处理其他测试订单。
如果您的读卡器仍无法工作，请联系 Shopify 支持团队。如果读卡器出现问题，您也可以查阅制造商的安装和操作手册。

Where to buy the Swipe (Lightning) card reader
The Swipe (Lightning) card reader is available from the Shopify Hardware Store in Canada.
Install the Swipe (Lightning) card reader
To install the card reader, attach the lightning connector to your iPad or iPhone. You can use the plastic adaptors provided with the reader to make sure that it's secure.
To charge your iPhone or iPad while using the card reader, connect the supplied micro-USB cable to the card reader's pass-through micro-USB port.
How to swipe a card
Swipe the credit card across the card reader with the card's magnetic strip facing away from you:
Troubleshooting
If your card reader isn't working, go through the following steps with a test order for a 1.00 quick sale item (you can refund the order later).
Steps:
Check that you have an internet connection. Shopify POS needs to connect to the internet through Wi-Fi or your device's cellular data to process payments. If you can't connect to the internet, then you can't process card payments.
Are you using a compatible payment provider and currency? You can use the Swipe (Lightning) card reader only if:
If one of those requirements isn't true for you, then you need to take the credit card payments using an supported card reader.
your store is based in the United States or Canada
you're using a compatible payment provider
your store's currency in USD or CAD.
Make sure that you're tapping Credit at the payments screen. The External terminal payment option is only for if you're using an external payment terminal instead of a Shopify-supported card reader.
Check that the reader is correctly plugged into your POS device and that the device's case is not in the way.
Make sure that you're swiping the card correctly, with the magnetic strip facing away from you.
After tapping Credit on the payments screen, unplug the card reader, and then plug it into the POS device again. Check that you see a Card reader connected notification.
Try entering the credit card information manually. If this works, then there is a problem with the card reader.
If the manual entry doesn't work, then force quit the Shopify POS app, turn off the device, and unplug the card reader. Turn the device back on, open Shopify POS, plug in the card reader, and try another test order.
If your card reader is still not working, then contact Shopify Support. You can also consult the manufacturer's Installation and Operation Manual if you have problems with your card reader.
