From November, the way you pay bus and tram fares changes. The current system - MyWay - gives way to MyWay+.
At the moment, you need a card, loaded with money, to tap on and tap off each journey. Under the new system, you can tap with a debit or credit card (including one connected to a phone or smartwatch). Old-style cards will still be available for those who don't want to use the more direct method.
