Why can't ETC be removed?

[DiDonovan]

The reason why ETC cannot be removed is: On the back of the ETC device, which is the side attached to the car's front windshield, there is a small button. Before installation, this button protrudes outward. When the device is pressed tightly onto the windshield, the button is pressed in, acting like a switch that activates the internal system of the ETC. In this state, the device is ready to be activated, and vehicle information can then be transmitted to the ETC device via Bluetooth from a mobile phone, saved in memory, enabling automatic toll payments on highways. If the device is removed from the car, meaning it is detached from the front windshield, the small button will pop back up, effectively shutting down the ETC's internal system. The ETC will stop working, and all stored vehicle information, including linked bank card details, will be lost. Even if the device is reattached, the information will no longer be present, rendering it unusable. The original intention behind this design is to: Protect the financial security of all vehicle owners. An ETC device can only be used independently by the one vehicle it is bound to. In other words, only the highway tolls for this specific vehicle will be deducted from the linked bank card via the fixed ETC device. This thoroughly safeguards the owner's funds, preventing financial losses or bank card information leaks in case the ETC device is lost or stolen. Hence, ETC devices cannot be casually removed. Prevent arbitrary borrowing among users. This design effectively saves vehicle owners a lot of hassle. Different vehicle types have varying highway toll rates, so ETC devices are dedicated to specific vehicles, ensuring one-to-one correspondence. The anti-removal feature guarantees accurate toll charges. If ETC devices could be freely removed, many friends and relatives might want to borrow them, potentially leading to one person's ETC being shared among many. This would create significant inconvenience for the owner. Therefore, ETC devices cannot be casually removed.
