Square 信用卡读卡器如何工作？
The Square card reader is a device that connects to your smartphone or tablet via the headphone jack, enabling you to take credit card payments. When a card is swiped through the device, it reads the details and processes the transaction through the Square app. All card details are encrypted for security, with transaction details visible on the Square dashboard for easy tracking and management.
