You're correct, there are a bunch of different ticket options. Not sure about how it's actually implemented, though.
Slightly tangential, but when I was in Montreal, I was blown away that you just purchase a ticket from a machine and you get a printed out ticket with an NFC chip inside. Not my favourite part of the trip (Montreal is beautiful!) but definitely a cool piece of technology to see being put to such a mundane use.
