If you already have an ETC charge card, you can go to CCB to tie a savings card or a credit card to withhold the handling fee. CCB seems to have issued ETC credit cards in most provinces and cities, such as Sichuan Tianfu Changxing Long Card, Shandong Lutong Long Card Automobile Card, Liaoning Liaotong Long Card, Guangdong Yuetong Long Card, Hunan Xiangtong Long Card, Hebei ETC Credit Card, Shanghai Hutong Long Card, Jiangsu Sutong Long Card/Traffic Credit Card, Anhui ETC Credit Card, Jiangxi Gantong Long Card, Shaanxi Sanqintong Long Card, Beijing Jingtong Long Card and Gansu Long Yuan Traffic Long Card. It is to load the ETC charge-to-account function in the credit card chip, that is, the credit card is also an ETC charge-to-account card. This card does not need to be recharged in advance. The card is directly inserted into OBU, and the high-speed toll is directly deducted from ETC credit card, just like usual consumption. It is best to recharge the account first and then repay it. There is also an ETC credit card, but it needs to be recharged in advance and cannot be deducted directly from the credit card, which is a bit troublesome. So when I applied at the outlet, I finally asked the staff.
