What type of charging cable does ETC use?

[DiAaron]

ETC uses a data cable with a USB interface for charging, which is also the connection port used by staff to input vehicle information into the ETC device. How ETC works: Through the onboard electronic tag installed on the vehicle's windshield, it communicates via dedicated short-range communication with the microwave antenna in the ETC lane at toll stations. It utilizes computer networking technology to perform backend settlement processing with banks, enabling vehicles to pass through highway or bridge toll stations without stopping while still paying the required fees. The ETC installation process is as follows: Upon receiving the device, first check if the ETC card and electronic tag (OBU) are damaged. Press the anti-tamper button on the back of the OBU; a red light will briefly illuminate, and the OLED screen will display 'Tag Invalid' or 'Please Insert Card,' indicating the device is functioning normally. Clean the front windshield, ensuring the glass surface is smooth, clean, and dry. Then peel off the adhesive backing on the OBU and attach it to the installation position. Press firmly for 2-3 minutes to remove any air bubbles. Insert the ETC card with the front side facing the driver and the back side facing the windshield, ensuring the chip is properly inserted into the OBU device.
