My joint Taobao card of Postal Savings Bank has been useless for three years, and the card is gone. I don't know if there will be adverse consequences if it is left like this, and will it be cancelled by itself? Hello, the Taobao card of China Postal Savings Bank will not affect the credit of customers; If there is no other business in your account, the Postal Savings Bank will automatically close the account when the management fee owed by the small account reaches 12 yuan, the account balance is zero, and the conditions of long-term fixed account (the last transaction of personal current deposit account is determined to be a long-term fixed account for more than 2 years) are met; I hope my answer is helpful to you.
