The offered inquiry system is established in order to prevent unsanctioned access to information about toll road users.
The choice of the mobile carrier is based on the conditions established by the supplier of this service.
The SMS inquiry service makes it possible for users having telephone numbers of other countries to receive their balance information.
“When a vehicle passes a toll collection station, money is written off directly from the balance of a respective OBU, then the data are transferred to the central system to be recorded there. Therefore, information about the actual balance is stored in the device memory, and it can only be retrieved with the use of a special terminal installed at a costomer service point.” Therefore, information about the OBU-balance received from the BelToll Infoline, personal account on the website, or an SMS inquiry, is always treated as reference information.
