You can change the bound account in real time by using the "Change Card" function on the home page of the ETC function of BOC's personal mobile banking. Please make sure that your current bound account is not in arrears with the toll, and the new China bank card is in normal condition. If your old binding account is a BOC debit card and a certain amount of deposit has been frozen, the deposit of this card will be automatically unfrozen after the successful binding.
