I previously applied for the CCB ETC Dragon Credit Card. This credit card has an ETC function. To use the ETC function, you must recharge the ETC account in the card. It is not a bookkeeping type. At that time, if you recharge 1,000, you can get OBU equipment as a gift. So this should be deducting 1,000 yuan from the credit limit and recharging it to the ETC account. When crossing the expressway, take the ETC channel and deduct the money directly from the card. It’s best to pay attention to CCB’s bills in the future and don’t forget to repay.
