Helsinki Metro Ticket Widget for Android
The widget uses the SMS read permission to check when the ticket you received expires. The application does not have permission to use Internet or other means of sending or receiving messages making the app very safe to use.
By clicking the M button you are taken to your SMS application with prefilled number (16355) and message content (A1). The ticket can be opened by clicking the remaining time when you have a valid ticket.
The ticket can also be used in trams around Helsinki city and some other public transports. For more information about Helsinki city mobile ticket please visit: http://www.hsl.fi/en/tickets-and-fares/mobile-ticket
