The fair collection has been revamped. It could be better, but I've also seen worse.
Single Ticket Fares
Single tickets are printed on a piece of thick cardstock. They are both used for a proof and transfer. Validation is electronic by inserting it into a machine on a bus or at a terminal of up to 2 hours. The machine prints the times it was used on the ticket.
Multiday tickets are printed on some thin plastic-like paper with an NFC chip inside. They are tapped on terminals and in busses and get no physical markings of when they were used, but are validated 100% digitally with some central system. They are also good for the same type of transfer.
Monthly/Yearly passes are a thick plastic credit-card-like card. They have an NFC chip and work similarly to the multiday tickets.
