ETC displays the recharge card, and then the screen is black.

ETC shows that the prepaid card represents the success of the call, and if the display logo is invalid, the call is confirmed to have failed. As for why ETC shows that the recharge card then crashes, it is likely that the machinery and equipment have loosened or fallen. If you feel that there is a problem, you can apply for the information of ETC's business outlets to see if it is necessary to talk about it again.

If the rfid tag shows that the logo is invalid, it means that the call is not yet available. If you don't understand that the call is unsuccessful, you'd better go to ETC outlets and ask the management to help install the call.

For ETC equipment, once installed, it is best not to touch or move parts. This will invalidate ETC. If you want to apply it again, you must reinstall it.

For cyclists, the installation of ETC provides convenience for him to travel, saves a certain amount of time, and at the same time has a certain guarantee effect on the car, reducing fuel consumption and the damage of its brake system, and also helps to reduce exhaust emissions. But at the same time, there are some puzzles, such as being opportunistic by criminals, stealing money from their credit cards, and cheating according to mobile phone text messages. But we can take some effective measures to nip in the bud.

For example, in the case of stolen credit cards, we can turn off the visa-free function of confidential payment for small loans, pull out the card when getting off the bus and turn on the SMS notification function. When the credit card money is stolen, we can call the financial institution at the first time to report the loss or apply for compensation.

For fraudulent SMS, everyone will encounter it at other levels except ETC. In this case, you should make a phone call to determine whether the matter is conclusive, and then proceed to the next practical operation.
