The method to reactivate an ETC card after removal is: Insert the side with the chip facing upwards into the card slot of the ETC sensor. If the message "Start Accounting" appears, it indicates successful activation. ETC is an Electronic Toll Collection system, also known as an Automatic Road Charging System, specifically designed for toll roads. It is commonly used on highways, toll bridges or tunnels, and certain sections of urban roads to alleviate traffic congestion. The working principle of ETC is: It uses automatic vehicle identification technology to establish wireless data communication between the vehicle and the toll station, enabling automatic vehicle recognition and the exchange of relevant toll data. Computer networks are employed to process the toll data, achieving a fully automatic electronic toll collection system without the need for stopping or toll booths.

I've been driving long-haul trucks for ten years, and reactivating an ETC card after removal is simple: just reinsert the card face up into the vehicle's onboard unit slot until you hear a 'beep' to activate it. However, avoid unnecessary removal to prevent poor contact or device wear. If there's no response after reinsertion, check the unit's power light—a steady green light indicates normal operation, while a red light may mean low battery (try charging via USB). If that doesn't work, power off the device, wait one minute to restart, or press the reset button (a small hole on the back) for 5 seconds. Remember, frequent insertion/removal increases failure risk—clean oxidized cards with an eraser before reinsertion. For unresolved issues, call ETC customer service at 95022, provide your license plate and card number, and they can remotely reactivate it. This issue often occurs due to accidental post-parking handling; keep a backup device ready to avoid highway delays.

I have been working with automotive electronic devices for a long time. To activate an ETC card, follow these steps: First, ensure the card is intact and inserted firmly into the device with the front side facing the device. If there is no prompt sound, check the OBU light—it should normally show a green light. If there is no light, it may indicate a power issue; unplug the power cable and reconnect it or charge for half an hour. If the device freezes, use a needle to press and hold the reset hole to restore default settings. For system-linked apps like ETC Assistant, log in and rebind the device if necessary. For prevention, avoid frequently removing the card before parking and clean the card slot if it accumulates dust. A loose card can affect signal transmission, so it's recommended to secure it with tape. If the issue persists, contact a service point to check the circuit board or replace the card. This ensures efficient and time-saving highway passage.

When I first started driving, I was also curious and pulled out the ETC card. Reactivating it is easy: just insert it back into the device slot, and it will work when the indicator light turns on. If it doesn't fit tightly, try pressing it all the way in; if the light doesn't turn on, check the USB charging port—it should work as long as the battery is fine. If the device malfunctions, call customer service and provide your license plate number for reactivation. Avoid pulling it out casually to prevent damage—it saves money and makes travel more convenient.
