Don't worry, Apple won't write off money from your Account or credit card. The system simply needs to check the authenticity of payment information.

This happens after creating a new Apple ID account when you bind a new bank card when the card is reissued by the bank instead of the old one with expired validity.

After entering the payment information, the bank can temporarily block a small amount (usually equivalent to $ 1). This happens to check the positive balance of the Account. This amount is refunded to the Account in a few hours/days.

Once the card is confirmed, you can download the update / other applications.

If for some reason, you do not want or can not confirm the payment information, you can always create a new Apple ID without a linked card or Account.
