The steps to bind a credit card are as follows:

Find a new UnionPay payment method

Open the App Store application on your mobile phone and go to the "Recommended Products" page at the end of the homepage Find your Apple ID, click to select, and select "View Apple ID" - "Payment Information" in the pop-up selection box, and you will see that the new payment method "UnionPay" has appeared.

Domestically issued credit cards or debit cards can be bound, and the system will automatically identify the card type. As shown in Figure 3 below, the author's MasterCard credit card number starting with the number "5" was successfully recognized. Binding a credit card requires filling in information such as card number, security code, expiration date, etc. Binding a debit card is much simpler, as you only need to fill in the card number and phone number.

2. Bind bank card

Select the "UnionPay" option, fill in the card number, mobile phone and other information as required at the bottom of the page, and you will receive a verification text message from the bank—— There is no need to activate online banking for the bank card, but the mobile phone number must be consistent with the one registered with the bank. Successful verification means that the binding is successful, and there will be no confirmation page similar to "Binding Successful". If you want to manually check whether the binding is successful, you can enter the "Payment Information" page again. At this time, you will see that the bank card number has changed to "black dots + the last four digits of the card number", which means the binding has been successful.
