Lol. The last time I was in Paris, I must have lost 20-30€ of metro tickets. I kept the tickets in the same pocket as my smart phone, and when I took it out of my pocket the tickets would fall out with it. Having lived there on and off over the years I still have the yellow and later purple tickets, some of them unused. Anyway, ideally it would be nice to have an NFC style solution where you would be charged on exit (for the metro/RER at least) so that you would not have to figure out the proper fare ahead of time. Bus would be a flat rate. And while we are at it, make the fare system simpler (though some old-timers may remember when you needed multiple tickets for long, multi-zone bus rides -- at least those days are gone).
