Traveling from A-to-B has never been easier, as the user only needs a smartphone in his pocket. No more missing change to buy a ticket or thinking about fare zones. Travel first, get charged automatically the best price afterward. We think the future of transportation lies in easy traveling, achieved by seamlessly combining different transport modes. We provide an oyster card-like ticketing system without additional infrastructure: easy to scale, cost-efficient and simple access for the end-user. Through machine learning on smartphone sensor data we passively detect ten different transport types in the background. By integrating APIs and further data sources, we provide a fully software-based ticketing technology that works as a check-in/be-out solution. Our platform is designed to easily integrate public transportation and other mobility services such as car-sharing solutions. It enables Mobility-as-a-Service in a pay-as-you-go manner, not forcing the user to plan his future mobility demand. Besides increasing the attractiveness of the transport system through state-of-the-art ticketing, our platform generates accurate multimodal data that can be used to improve the existing transport system: optimize timetables and routes, enable flexible pricing schemes, and finally focus the mobility system around the user.
