If the card is not used, the service fee will be deducted. For example, if the balance on the card of China Bank is less than that of 300 yuan, the money will be deducted. For example, when online banking is launched, there will be an annual fee deduction, while CCB's is an annual 50 yuan. There is also the cost of mobile phone notification (if it is not opened, it will not be deducted. After opening this service, send SMS to the mobile phone for deposit and withdrawal, and deduct 3 yuan every month). . If you don't use this card for a long time, you can cancel it and everything will be fine. Now I'm a sophomore. If I remember the password, I can go directly to the Bank of Communications to deposit money. I'll know if I can use it. If you can't remember the password, you can go to the branch where the school opened an account for you and redesign the password with your ID card. Remember, the password must be changed by the branch applying for account opening.
