The project involves the modernization of the e-ticketing system on buses, which includes the procurement of equipment and the development of software solutions. The existing e-ticketing system is outdated, spare parts are almost impossible to obtain, and it is very difficult to ensure that enough vehicles are equipped with functioning and complete ticketing equipment to maintain the timetable. For this reason, it is necessary to modernize the e-ticketing system, which involves procuring complete hardware – equipment for vehicles, accompanying devices, servers, and others, as well as accompanying software systems/programs.
