Payment of transport or parking services can be done both through Premium SMS, and via the SEJF. SEJF mobile application is used as a payment instrument which, thanks to the technology of smartphones brings a number of improvements and benefits not only for users - residents and visitors to the city, but also for the recipients of such payments, ie to transport operators and parking.
The entire back office system is the same for Premium SMS and SEJF. System is ONLINE, modular and allows the flexibility to add new modules and additional functionality.
