Which manufacturers produce automotive ETC devices?
2 Answers
Common manufacturers producing ETC devices include JinYi Technology, Wanji Technology, COSCO SHIPPING Technology, and Wantong Technology. ETC working principle: Through dedicated short-range communication between the on-board electronic tag installed on the vehicle's windshield and the microwave antenna in the ETC lane at toll stations, computer networking technology is used to conduct background settlement processing with banks. This achieves the purpose of vehicles passing through highway or bridge toll stations without stopping while still paying the required fees. ETC usage precautions: The ETC transaction sensing range is 8 meters. When encountering a stationary vehicle ahead, maintain a distance of over 10 meters to prevent automatic fee deduction for the preceding vehicle in case its ETC device malfunctions or is absent. The recognized speed for ETC lane passage is 20km/h. Excessive speed may prevent reading of vehicle device information and cause fee deduction failure. Unauthorized removal or relocation of OBU devices, or detachment/loosening of ETC electronic tags will render the tags invalid. These can be tested at the bank where the ETC card was issued or at highway service centers. For non-human-caused loosening or detachment, simple reactivation suffices. When using debit cards bound to ETC, insufficient balance may cause fee deduction failure. Follow on-site staff guidance to use manual MTC lanes with cash or card payment. Excessively thick windshields may cause poor signal reception, particularly for vehicles that have undergone accident repairs with windshield replacement or aftermarket windshield modifications.
I recently installed an ETC device in my car. The main manufacturers are JinYi Technology and Wanji Technology, which are two major brands quite common in the market. During installation, the staff told me that these devices are all produced by domestic brands, with reliable quality, and can also enjoy discounts on highways. JinYi's device is more compact and suitable for compact cars, while Wanji's is slightly larger but has better sensitivity—either choice is fine. They are usually given for free when purchased online or when applying for a card at a bank. In actual use, the signal is occasionally unstable, but overall, it’s very convenient and saves queuing time. If you're concerned about compatibility, you can check the manufacturer information on the label at the back of the device—generally, those from formal channels are reliable. Regularly check the battery status to avoid failure, making long-distance drives much more worry-free.
