Where is the charge for in-app purchases?

Apple's App Store is bound with an Apple ID. You can use the balance in your Apple ID or pay by credit card.

The operation process is as follows:

First, on your iOS device, open the App Store application, find your Apple ID at the bottom of the boutique recommendation page, click, select View Apple ID in the pop-up prompt box, and then enter the password of your Apple ID.

After successfully logging in, we click to enter the payment information, and then we can see the new payment method "UnionPay UnionPay". After selecting UnionPay, enter your UnionPay card number below (note that domestic credit cards or savings cards can be bound, and the system will automatically identify the card type), and then a small UnionPay logo will appear in the upper right corner of the card number, indicating that the card has been successfully identified. You need to fill in some personal information below. Of course, if a credit card is bound, you need to fill in additional information such as card number, security code and expiration date.

After filling in the relevant information, we will receive the verification information from the bank. Note: the bank card does not need to open online banking, but the mobile phone number must be consistent with the bank registration. Successful verification means successful binding, and there will be no special confirmation page like "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 becomes a black dot+the last four digits of the card number, indicating that the binding is successful.
