[Leanne]

On December 21, 2014, according to the arrangement of the Ministry of Transport, the ETC national networking system in 14 provinces and cities including Beijing, Tianjin, Hebei, Shandong, Shanxi, Shanghai, Jiangsu, Zhejiang, Anhui, Fujian, Jiangxi, Liaoning, Shaanxi, and Hunan completed the switching test and officially began trial operation. How ETC works: Through dedicated short-range communication between the on-board electronic tag installed on the vehicle's windshield and the microwave antenna on the ETC lane at the toll station, computer networking technology is used to conduct background settlement processing with the bank, thereby achieving the purpose of vehicles passing through highway or bridge toll stations without stopping while still being able to pay the highway or bridge fees. Where can ETC be installed: For small vehicles such as cars and minivans, the OBU device is installed in the upper middle part of the front windshield, while for large vehicles such as trucks and buses, the installation position is in the lower middle part. ETC installation position requirements: The height should not be less than 1.2 meters or higher 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).
