The answer is yes, but don't be surprised if you have not heard anything about the Mobilis travel card. It is probably the least advertised travel card on the market in Paris, which is strange considering it is offered by the RATP. The mobilis card lasts for 1 day from 05:30am on the day you validate the card - presumably until midnight.
It costs €6.80 (Euros) and gives you unlimited use of the metro, buses and trams on zones 1-2 throughout the day and there is no peak restriction. The most popular method of travelling on the metro is to buy a carnet of 10 tickets which costs €13.70 (Euros). This gives 10 individual single journeys but the tickets cannot be used on the metro and then on a bus if you want to change your mode of transport halfway through your journey. If you plan to make at least 6 journeys in a day, the mobilis is good value for money.
They can be purchased in any metro automatic ticket machine or at stations. Different zones are available but you cannot use them to get to the airports.
