    A greater risk is that the machine doesn't take notes at all, though. Commented Aug 22, 2019 at 12:35

    Tickets for what?! Presumably not plane tickets, perhaps you mean train tickets?

    In any case if the ticket machine does not accept the notes you can buy yout tickets at the train station office so it will be fine anyway :)

    Contrary to the US for instance, vending machines which take notes are quite rare in France (and probably in most of Europe, I’d say, though this may be an overstatement). Coins and cards are the common accepted modes (more and more often only cards, actually). RATP (which operates the Paris metro and most bus and tram lines, and part of the RER network, but not the branch to CDG) has some, but I don’t think SNCF (which operates RER in CDG) does.

The RER vending machines will probably only accept coins and card payments and no bank notes at all. At the airport, there are however staffed ticket counters where you can buy a ticket and pay cash and get proper change.
