I visited a few European countries this past summer and Paris was definitely not the best in terms of public transport tickets. I had to buy the paper 3 day visitor pass from Orly after finding no way as an iPhone user to purchase a ticket on the Île-de-France Mobilités app or their website. Constant fear of losing my $50 euro investment that's a mere 6.5cm x 3cm rectangle. Some cities had the tap to pay gates which were by far the most convenient option as an Apple Pay user. Others like Berlin or Wien had working mobile tickets.
