排查付款接收问题
如果您的读卡器似乎在工作但无法处理付款，请按照以下步骤来排查问题：
确保您采用的是正确的插卡方式。
如果您位于加拿大，并且读卡器拒绝 Interac 感应式支付，请确认使用卡付款的金额小于 100 加元，使用 Apple Pay 或 Google Pay 钱包账户付款的金额小于 200 加元。
强制退出 Shopify POS 应用，然后关闭设备。重新打开设备，打开 Shopify POS，并确保已重新连接读卡器。当读卡器的状态指示灯显示读卡器已连接时，尝试使用其他测试订单。
尝试通过针孔重置读卡器。针孔位于读卡器顶部，电源按钮旁边。将尖细的物体（例如回形针的尾端）插入孔中并按压五秒钟，以重置读卡器。
如果您的读卡器仍无法工作，请点击 ≡ > 客服 > 发送报告，向 Shopify 客服发送报告。客服将在您提交报告后与您联系。

Troubleshoot payment acceptance
If your card reader appears to be working, but isn't processing payments, then investigate the problem using the following steps:
Make sure that you're inserting the card correctly.
If you're in Canada and the card reader is declining an Interac tap payment, then confirm that the amount is for less than 100 CAD for a card payment or 200 CAD for an Apple Pay or Google Pay wallet account.
Force quit the Shopify POS app and then turn off the device. Turn the device back on, open Shopify POS, and make sure that the card reader has reconnected. When the card reader's status light shows that the reader is connected, try another test order.
Attempt a pinhole reset of your reader. The pinhole is located on the top of the reader, next to the power button. Insert a thin pointed object, such as the end of a paper clip, into the hole and press down for five seconds to reset the reader.
If your card reader is still not working, then send a report to Shopify Support by tapping ≡ > Support > Send a Report. Support will contact you after the report has been submitted.
