Compound Pass Card (CPC) card
Product introduction
Highway compound toll card is also called Compound Pass Card (CPC) card, and its network application is one of the basic and core works for the pilot project of canceling toll stations at provincial boundaries of expressways. Different from the previous IC toll cards, CPC cards can not only identify the information of vehicles entering and exiting toll stations, but also accurately record the actual driving path of vehicles by setting up a path identification system at the interconnecting locations of the expressway network.In the closed toll road environment, by picking up the CPC card at the entrance, and returning it at the exit, MTC vehicles can achieve "provincial billing, unified charging" based on 5.8GHz DSRC technology through the CPC card .
