When users apply for cancellation, they should provide the valid ID of the original applicant and go to the ETC customer service outlet of the original issuer for processing. Specific method: Car owners need to bring their ID card, driving license, ETC pass, driver's license, and ETC-bound bank card to a bank branch or ETC management department to cancel. Then the staff will ask you to fill out a highway non-stop toll etc. agreement, and you can unbundle it by checking the cancel button.
