One-click credit card payment is a safe and fast payment method introduced by Amazon China. With this payment method, you don't need to log in to online banking every time to pay, just save credit card information (bank card number, cardholder's name, credit card expiration date and other information) in your Amazon account in advance. After saving successfully, you can choose to use the saved credit card for one-click credit card payment every time you place an order. After the order is placed successfully, the bank will automatically deduct the amount of the corresponding package from your credit card when the package is delivered. It always feels a little dangerous.
