For example, the Xiangtong Dragon Card issued by Hunan Province can still go to ETC if it is cancelled by a credit card and the signing account is changed at a designated outlet of CCB. Only after the credit card function is cancelled, it is equivalent to an ETC stored value card. You have to deposit the money in the ETC prepaid card of this card first, and then go to ETC, and deduct it from the stored value every time. However, for example, the IC credit card of Sanqintonglong Card issued by Shaanxi, if the credit card is cancelled by calling the customer service hotline of CCB, the ETC function will be cancelled at the same time and can no longer be used. Therefore, it is suggested that the landlord ask the local CCB.
