It should be that there is something wrong with your bank card, such as the type of bank card is not supported, or the bank card is in an abnormal state. If your Tik Tok has real-name authentication, then the bound bank card must be consistent with the real-name authentication information. So I suggest you bind other bank cards.

1. Open Tik Tok and click the menu in the upper right corner.

2. Click on the wallet.

3. Click on the bank card.

4. Add a bank card.
