It turns out that the credit card of Bank of Communications has expired. Why can't I use a new card on Taobao?

After the credit card expires, you need to re-enter the binding, because the validity period and security code have changed.

The steps for rebinding the bank card are as follows:

1. On Alipay my page, find the item "Bank Card" and click Enter.

2. After entering my bank card page, find the "+"sign in the upper right corner of the page and click Enter.

3. After entering the Add Bank Card page, enter the bank card number.

4. Then fill in the reserved mobile phone number of the bank card, click the agreement and tie the card.

5. Then enter the verification code sent by the system to the mobile phone.

6. After verification, the card will be bound to Alipay.
