It is abnormal that the screen of ETC card plug-in is not bright. The ETC card is activated successfully. When the ETC card is inserted, the corresponding vehicle information will be displayed or the account balance of the ETC card is normal. Some ETC devices will have corresponding work indicators. If the screen is not bright, pressing the top button or inserting the ETC card does not respond, and the ETC device may be out of power or damaged.

Only ETC devices and ETC cards can be brought to the nearby ETC service outlets for testing. If they are not artificially damaged, they can be reactivated or replaced.

The flashing red light of ETC equipment is mainly caused by the ETC card not being inserted in place. If you insert ETC, the green light flashes, and then there is a corresponding prompt, such as whether the card is a prepaid card or a savings card.

ETC is a non-stop electronic toll collection system.

Insert the ETC card into the ETC electronic tag, and communicate with the microwave equipment in the ETC lane through the electronic tag to realize the function of paying the expressway toll without stopping. Nowadays, this form of charging is becoming more and more popular, which replaces the manual charging of parking, changes the congestion phenomenon of long queues in the past, saves the waiting time of car owners and improves the speed of vehicles passing through toll booths.

However, at present, there are still one or two artificial channels in the toll station, because there are still a small number of people who have not installed ETC. When some people have insufficient ETC balance or malfunction, they can choose artificial channels.
