If you are staying at a hotel, youth hostel or campsite in Geneva, the establishment may offer a "Geneva Transport Card", which gives free access to public transport in Geneva. Get more information from Genève Tourisme or the establishment concerned.
Geneva's public transport system is operated by the Transports publics genevois (TPG). Their site has timetables, fares, route details, etc. Unless you have a weekly or monthly pass, you have to buy your ticket at the machine located at the bus stop, if possible with the exact change. Tickets are not sold on buses. The machines accept CHF and EUR.
Various outlets - including TPG agencies and newspaper shops - sell prepaid cards (Cart@bonus) that can be used instead of money to buy tickets from the machines at bus stops.
