You saved your credit card information the first time you used it, so you don't need to re-enter it for shopping in the future. If someone else logs into your Amazon account, you can't buy anything for yourself, because every time you want to send an order to a new address, Amazon will ask you to re-enter your credit card information. So even if someone invades your account, you can't send the order to his address with a credit card. The setting of "one-click order" is similar: one-click order setting includes two parts: delivery address and credit card. The intruder either chooses an address that has already saved you, or has to re-enter the credit card information.

Also, after you add the credit card information to Amazon, you will never see your complete card number on Amazon. Any place that displays credit card information will only display the last four digits of the card number, thus ensuring that even if others log in to your account, you can't get your complete credit card information.

To sum up, Amazon credit card payment is absolutely safe.

When the order status is "about to be shipped", Amazon will inform the bank to freeze the available amount of the package amount corresponding to your debit card.

When the order status is "from the warehouse", Amazon will inform the bank to deduct the corresponding package amount from your debit card.

Amazon has a world-class risk control system and a professional risk control team. It will strictly follow the PCI-DSS certification and implement multiple protection measures to protect customers' credit card information. Very safe, much more reliable than domestic websites.
