Vehicle-Mounted ETC On-Board Unit (OBU)

This ETC on-board unit (OBU) is a compact electronic toll tag installed on the vehicle's windshield. It communicates with the toll booth antenna via 5.8 GHz DSRC microwave technology, enabling automatic, non-stop toll deduction without stopping or handling cash. The low-profile plastic housing fits neatly behind the rearview mirror, while the built-in battery provides long standby life and low power consumption. Simply stick it to the windshield, pair it with your ETC account, and pass through ETC lanes smoothly for faster, more convenient highway travel.
