ETC is not affected by the expiration of the bound credit card, so it can naturally continue to be used. It's just that if the bound credit card expires, it will be invalid and can't be used. Customers need to change the card binding in time, otherwise the high-speed system will have no funds to deduct ETC tolls, which will lead to the failure of customers' payment, which is likely to be pulled into the "high-speed blacklist" and then it will be difficult to pass at high speed.

Usually, as long as the customer's credit card is in good condition, the issuing bank will replace it with a new card, activate it after the customer gets the new card, and then bind the new card to ETC (the old card limit and bill arrears are directly carried forward to the new card). The reason for rebinding ETC is that after the credit card expires, the security code will change and the card number may also change. If it is not rebinding, ETC will not be able to deduct the fee.

Electronic toll collection (ETC) is one of the service functions of intelligent transportation system, which is especially suitable for use in highway or bridge and tunnel environment with heavy traffic. There is a special ETC toll collection channel at the expressway toll collection office. As long as the owner installs an induction card on the front windshield of the vehicle and pre-stores the fees, there is no need to pay or stop manually when passing through the toll booth, and the high-speed toll will be automatically deducted from the card, which can realize automatic charging.

The fully automatic electronic toll collection system takes less than two seconds to charge each vehicle, and the capacity of its toll collection channel is 5 to 10 times that of the manual toll collection channel. The use of automatic electronic toll collection system can make expressway toll collection move towards paperless and cashless management, fundamentally put an end to the loss of toll tickets and solve the financial management confusion in expressway toll collection. In addition, the implementation of fully automatic electronic toll collection system can also save capital construction costs and management costs.

ETC is an electronic automatic toll collection system for highways, bridges and tunnels that is being developed and popularized internationally. This technology has a long history of development abroad, and the electronic toll collection systems in many countries and regions such as the United States and Europe have been partially networked, and economies of scale have gradually formed. Undoubtedly, China's expressway network toll collection method with IC card and magnetic card as media and manual toll collection method is also influenced by this trend.
