What does ETC expiration mean?

[MaggieDella]

ETC expiration may be caused by self-removal or relocation of the OBU device, ETC running out of power, or the ETC electronic tag falling off or becoming loose, all of which can render the ETC unusable. If a newly issued ETC shows an expired card, this is normal and does not affect activation. You can press the ETC anti-tamper switch on the back, and the red light will briefly turn on. The OLED display will show "ETC tag invalid," indicating that the ETC electronic tag is not activated, which is normal. ETC activation method: Insert and remove the ETC card twice in succession until the electronic tag screen displays "Bluetooth is on." If inserting and removing twice without the electronic tag attached displays "Tag invalid," this is normal and does not affect activation. Alternatively, you can directly press the button on top of the electronic tag to enable Bluetooth. Turn on your phone's Bluetooth, open the corresponding mobile app (usually a download QR code is provided on the electronic tag), and enter the device activation interface. Click "Connect device" and wait patiently for the "Connection successful" prompt. Once connected, upload a photo of the vehicle's front to complete activation.
