ETC applied for at a bank will generally be directly bound to the bank’s credit card (credit card). If the user wants to unbind or change the binding, he or she can apply directly to the bank. I hold the ETC card, ID card, and credit card (debit card) to be bound to the bank's offline branch, and then say that I want to handle the unbinding business, and the staff will help the user handle the business.

When users bind ETC to another card, they must confirm that the status of the newly bound card is normal, otherwise ETC deductions will be affected.
