What does the invalidation of the transit green card mean?
1 Answers
The invalidation of the transit green card refers to the failure of the ETC electronic display tag, which may be caused by the user's unauthorized removal or relocation of the OBU device or the loosening and detachment of the ETC electronic tag. The ETC is specialized and has a protective interlock during installation. There is a push-button switch on the side that adheres closely to the car's front windshield. If this switch is triggered twice consecutively, it will cause the ETC electronic tag to become invalid, meaning the transit green card is invalid. When receiving a new ETC device, after pressing the ETC anti-tamper switch on the back, the red light will briefly illuminate, and the OLED display will show "ETC tag invalid," indicating that the ETC electronic tag is not activated. This situation is normal.
