The Marseille fare system is very modern and fully automated. A 'Solo' ticket is valid for one hour and allows free transfer between metro, tram or bus as often as you like. The 'Carte Mistral' is a personal ticket and reloadable. It's 280 FF for one month and 52 FF for 7 days. All tickets have to be inserted into ticket machines even on buses, but these machines don't print anything on the tickets, so one never knows which tickets have been used and which have not.
