It may be that the bank card bill failed to be deducted successfully, which is a very common normal phenomenon. The problem here is that in the bank, due to system reasons, the bank that handles the card may not deduct the fee in time due to system reasons, which will lead to the safe passage of ETC, but it is found that the bank card does not deduct the fee. It is also possible that there is something wrong with the network or your bank card balance is insufficient. You can check the following contents and pay in official website. Under normal circumstances, it will not be hacked.

1, ETC is the automatic toll collection of expressway or bridge. The vehicle-mounted electronic tag installed on the windshield of the vehicle communicates with the microwave antenna on ETC lane of the toll station in a special short distance, and the computer networking technology is used to make background settlement with the bank, so that the vehicle can pay the highway or bridge toll without stopping. The system needs to install vehicle-mounted equipment carrying vehicle information on the vehicle. When the vehicle enters the entrance of the non-stop electronic toll collection channel, the station-level equipment of the expressway data acquisition and processing system reads the vehicle information in the vehicle-mounted equipment, calls up the matching vehicle data from the database, publishes, stores the records and uploads them to the data management center of the expressway data acquisition and processing system. The data management center analyzes the passing vehicles, forms a deduction transaction and uploads it to the bank in real time, and the bank returns to the data management center in real time after completing the transaction processing.

2.ETC system uses automatic vehicle identification technology to complete wireless data communication between vehicles and toll stations, and carries out automatic vehicle identification and exchange of related charging data. By using computer network to process the charging data, a fully automatic electronic charging system can be realized without stopping or setting a charging window.

3. Non-stop toll collection technology is especially suitable for expressway or bridge and tunnel environment with heavy traffic. The traditional non-stop toll collection system with lane isolation measures is usually called one-lane non-stop toll collection system, and the free-flow non-stop toll collection system without lane isolation is usually called free-flow non-stop toll collection system.
