Send to the terminal to inform the driver.

In addition, since the ETC database 41 in the ETC terminal controller 40 stores all the smart card information and has the respective smart card balance information, the ETC database 41 can be upgraded by upgrading the changed smart card information after payment. ).

As described above, when the vehicle passes through the toll gate on the toll road, the ETC system allows the vehicle to pay the toll automatically by using wireless communication between the vehicle-mounted device and the roadside base station, thereby preventing the vehicle from stalling at the toll gate to pay the toll. To prevent traffic jams, and to pay a fee automatically if the fee is not paid, it can help to collect the toll more accurately.

In addition, the smart card for paying a fee can be referred to as a fee payment means that can be used semi-permanently because it can be continuously charged and used whenever there is no remaining balance.

However, in order to use the smart card, a smart card should be inserted and recognized, and a terminal device for exchanging information should be included in the on-vehicle device, and the driver should check the balance of the smart card so as not to run out of balance.

Therefore, there may be a limit in minimizing the size of the vehicle mounting apparatus, and if the charging is not properly performed, there may be a problem in that a fee is not paid and a penalty is required.

In order to solve the above problems, the present invention is connected to a local server that manages electronic money through a communication network, rather than paying a fee using a smart card, and pays a toll charge in electronic money, thereby providing a terminal device for the smart card. It is possible to promote the miniaturization of on-vehicle devices by reducing the number of electronic devices, and to allow users to use electronic money using credit cards or bank transfers without recharging smart cards. Its purpose is to provide a used ETC payment system and method.
