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 the Use of Non-Stop Rapid Passage Systems," the ETC card must be inserted into the OBU device to work properly; 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 will need to reinsert the card when you need to use it. 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, toll bridges or tunnels, 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 onboard electronic tag (installed on the windshield) and the microwave antenna in the ETC lane, the system uses computer networking technology to settle payments with banks, enabling vehicles to pass toll stations without stopping. This is 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; Reduced wear and tear: Saves costs by minimizing frequent starts and stops, lowering vehicle wear and fuel consumption; Improved efficiency: ETC lanes can theoretically increase vehicle throughput 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, intercity transportation smart cards will be widely adopted in key urban clusters, and the proportion of vehicles equipped with ETC will significantly increase." The plan also set a target of "achieving a 50% ETC usage rate for road passenger vehicles by 2020." More future possibilities: In addition to continuously improving the convenience of ETC installation and usage rates for passenger vehicles, efforts will be made to promote ETC adoption for trucks and explore deeper integration of ETC systems with vehicle-to-vehicle communication, vehicle-to-infrastructure coordination, and other smart transportation developments. This will provide comprehensive travel services for vehicle owners, meaning more application scenarios will support ETC usage.

As a veteran driver who frequently takes long-distance trips, I recommend removing the ETC card when not in use. This is primarily to prevent theft risks. The ETC card is linked to a bank account, and if the car is stolen or parked in public, criminals may scan and deduct fees through the device. Last time I was on a business trip for a month without driving, I found hundreds of yuan had been deducted from my card when I returned. The device itself has a sleep function and doesn’t consume power, but removing the card for safekeeping is more secure. For long-term parking, removing the card can also prevent interface oxidation. If you use it weekly in daily life, leaving it in isn’t a big issue, but it’s best to develop a habit of regularly checking the card’s security—don’t find it troublesome. Safety first—don’t lose big for small gains.

For daily commuters, I think it's fine to leave the ETC card inserted when not in use. Keeping it plugged in is more convenient and ready for use anytime. The device will automatically go into sleep mode, which doesn't affect battery life. For someone like me who drives frequently with occasional days off, leaving the card in doesn't cause any issues. Constantly removing and reinserting the card may damage the interface, leading to costly repairs. However, if you won't be using it for an extended period, like during a weeks-long vacation, it's advisable to remove the card as a precaution. ETC is designed to be hassle-free, and keeping the card inserted saves time and effort. In case of sudden highway situations, you won't need to fumble with inserting the card.

From a technical perspective, ETC devices are designed with a low-power mode, consuming almost no electricity when the card is not in use. Removing the card is unnecessary and may wear out the slot. For short-term parking, such as overnight, the card can simply be left in the device. It should only be removed if the vehicle will not be used for an extended period. The device automatically manages power, and the card itself does not consume additional energy. Frequent insertion and removal can lead to poor contact or damage to the card slot. Ensuring the ETC functions properly is more important than daily card removal, unless there is concern about extreme scenarios like vehicle theft.

From a cost-saving perspective, it's more economical to remove the ETC card when not in use. This prevents unauthorized card usage and unnecessary expenses. The maintenance interface costs several hundred each time, and removing the card helps prevent corrosion, extending its lifespan. However, frequent removal can be time-consuming and may disrupt schedules. I prefer removing and securely storing the card during trips or when parking exceeds two weeks. For short-term daily non-use, I ignore it to minimize additional costs. Proper card protection can avoid extra highway fee losses.
