What causes the ETC card reader to display a read error?
1 Answers
ETC displays a card read error for the following reasons: When passing through the ETC lane, the speed is too fast, and the information is not fully read. The signal between the device and the lane antenna is weak. The ETC card or onboard device is faulty. It is recommended to check it. How ETC works: Through the onboard electronic tag installed on the vehicle's windshield, it communicates with the microwave antenna in the ETC lane at the toll station via dedicated short-range communication. The computer network technology is used to process background settlements with the bank, enabling vehicles to pass through highway or bridge toll stations without stopping while paying the toll. ETC installation location: For small vehicles such as cars and minivans, the ETC card and OBU device are installed in the upper middle part of the front windshield. For large vehicles such as trucks and buses, the installation location is in the lower middle part. ETC installation requirements: The height should not be less than 1.2 meters or more than 2.5 meters; the installation angle N should be between 30º and 90º (the angle between the surface of the electronic tag and the horizontal plane).
