Or simply purchase a Mobilis ticket which is their version of a One Day

buy a magnetic ticket as necessary. You then date it and write on the ID

I used one of those a few years ago, but not on buses. It was good value
for the trips I made on the day, and I was surprised that it isn't
publicised to tourists (or not noticeably). They plug the Paris Visite
pass in the tourist literature, but not Mobilis.

The Paris Visite pass is quite useful if you are on a tourist visit, as
you get into most museums, etc, for free, too....
