Take UnionPay card as an example. The operation method of credit card is the same:

1. First, on the iOS device, open the App Store app that comes with it. At the bottom of the recommended product page, find Your Apple ID, after clicking it, select View Apple ID in the pop-up prompt box, and then you need to enter the password of your Apple ID;

2. After successfully logging in, click to enter the payment information. You can see the new payment method "UnionPay". After selecting UnionPay, enter your UnionPay card number below (note that domestically issued credit cards or debit cards can be bound, and the system will automatically identify the card type), and then enter the card number in A small UnionPay logo appears in the upper right corner, which means the card has been successfully recognized.

You need to fill in some relevant personal information below. Of course, if it is bound to a credit card, you need to fill in additional information such as card number, security code, and validity period.

Note: If there is no "UnionPay" in the payment method list, then you only need to restart your phone.

3. After filling in the relevant information, we will receive a verification text message from the bank. Note: 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 the last four digits of the card number, which means the binding has been successful.
