One credit card can be exchanged and bound to 5 etc.

If the same credit card is used as a debit account, up to five ETCs can be bound. However, everyone needs to note that because ETC follows the principle of "one car, one card, one tag", a vehicle can only handle one ETC device, and one ETC device can only be bound to one bank card. Of course, if the customer has many cars in his name, the customer can apply for multiple ETCs. Cars, ETC, and cards are in one-to-one correspondence. Everyone also needs to be careful not to change the vehicle information and bound card number at will, otherwise it will affect the equipment and the highway will not be able to pass normally.
