Do I need to remove the ETC card when not in use?

It can be removed, but the ETC device will not function without it. According to the "Rules for Using the Non-Stop Rapid Passage System," the ETC card must be inserted into the OBU device for normal operation; otherwise, user information cannot be read. If the card is removed, you can use the manual lane and have the staff swipe the card for you. When the ETC card is inserted into the OBU device, a prompt sound will indicate that the device is activated. Without the card, the device remains in a dormant state and cannot recognize vehicle information at toll stations, so you need to reinsert the card when needed. ETC is the Electronic Toll Collection system, also known as the Automatic Road Toll System. It is a specialized road toll method used for toll roads, commonly seen on highways, bridges or tunnels with toll policies, and certain urban road sections to alleviate traffic congestion. ETC Billing Principle: Highways have one or more ETC lanes. Through dedicated short-range microwave communication between the vehicle's electronic tag (installed on the windshield) and the microwave antenna in the ETC lane at toll stations, the system uses computer networking technology to settle payments with banks. This allows vehicles to pass toll stations without stopping, based on the principle of "pass first, deduct later." Benefits of Installing ETC: Time-saving: Eliminates the hassle of waiting in queues; Green and eco-friendly: Reduces noise and exhaust emissions by allowing vehicles to pass toll stations without stopping, lowering pollution; Reduced wear and tear: Saves costs by minimizing vehicle starts and stops, reducing wear and fuel consumption; Improved efficiency: ETC lanes can theoretically increase traffic efficiency by 2-3 times, making traditional ETC faster, more advanced, and more high-tech. Compared to license plate payment, ETC technology is more mature and advantageous. More policy support: The State Council explicitly stated in the "13th Five-Year Plan for the Development of a Modern Comprehensive Transportation System" that "by 2020, the interoperability of transportation cards in key urban clusters will be basically achieved, and the proportion of vehicles equipped with ETC will significantly increase." It also set a target in the "13th Five-Year Plan" for comprehensive transportation development: "By 2020, the ETC usage rate for road passenger vehicles should reach 50%." More future possibilities: In addition to continuously improving the convenience of ETC installation and usage rates for passenger vehicles, future efforts will include promoting ETC usage for trucks and exploring deeper integration of the ETC system with smart transportation developments such as vehicle-to-vehicle communication and vehicle-to-infrastructure coordination. This will provide comprehensive travel services for vehicle owners, meaning more application scenarios will support ETC usage.

I found many friends have misunderstandings about ETC card operations. Whether to keep the card inserted in the onboard device depends on the situation: For daily commutes, there's no need to remove it at all, as frequent insertion and removal can easily damage the metal contacts or cause device loosening. However, if you're going on a long trip and leaving your car in an airport parking lot for half a month, it's advisable to take the card with you. Although the risk of ETC card theft is extremely low nowadays with dual-piece anti-tamper designs, since the card is linked to a bank card or account balance, it's better to be cautious during long-term parking. Last time I returned from a business trip, I found the device had been moved by a cleaner, and reactivating it was particularly troublesome.

When I first bought my car, I also struggled with this issue. Later, I specifically asked a bank friend about it. He said that during daily use, never foolishly pull out the card, as modern ETC devices have anti-theft spring mechanisms that automatically lock the card once inserted. However, in situations like needing to remove the glass for film replacement or selling a used car, remember to take out the card before handling the device. Otherwise, triggering the anti-theft lock will require a trip to the service outlet for unlocking. Additionally, a reminder: if you're using a debit card-type ETC, pulling out the card when the balance is insufficient won't allow for card recharging; you'll need to use the mobile app for that operation.

As an experienced driver who has dealt with device malfunctions, my advice is: regular car owners shouldn't bother. ETC devices are powered by solar energy, and that yellow indicator light keeps flashing all day after you remove the card, which actually drains the battery. Nowadays, newly issued ETC devices come with Bluetooth functionality, allowing activation and management via smartphone, making card removal completely unnecessary. Unless you notice the device on the windshield has become loose or detached—in which case you should send both the card and the entire device for repair—randomly inserting and removing it yourself could damage the induction coil.

A friend who works at a toll station mentioned that the most common ETC malfunction they deal with is device failure. Based on his observations, vehicle owners who frequently remove their cards are more prone to encountering issues. The chip on the ETC card acts as the device's brain, and each power cycle (removing and reinserting the card) wears down the components' lifespan. Particularly during the rainy season when humidity is high, the gap left by removing the card allows moisture to seep in, which can corrode the circuit board. If you must remove the card, it's advisable to do so on a dry, sunny day and immediately seal it in an anti-static bag afterward. Additionally, note that new banking regulations stipulate that if a card is separated from its device for more than 30 days, it will be automatically frozen, and reactivating it can be particularly troublesome.
