When you arrive at Charles de Gaulle airport you can get a train (RER) to the city centre. There are big queues for people buying tickets however there are automatic ticket dispensers. The only problem is that these machines only accept credit/debit cards with a chip or coins. The machines do not accept notes. So if you do not have a card with a chip or coins then expect to wait in a long queue for your ticket into Paris.
