EsTram Mobil allows users to utilize public transportation by creating virtual cards. The app provides information on public transport vehicles, stops, and schedules. Users can check and load balance onto city public transport cards through the application. It serves as a convenient tool for accessing transportation-related information on the go.

The app features permissions such as virtual card usage for public transportation, internet access for communication with the central system, NFC permission for reading Passenger Card IDs, vibration permission for NFC-enabled phones when reading Passenger Card IDs, sleep mode control permission for alert messages regarding balance limits, location permission for displaying location information on the map, and Google Cloud Messaging permission for balance checks to minimize phone battery and internet usage.
