Your card remembers. If you tap the same card or device all day, it calculates the cap automatically. You don’t even have to say “please.” It just does it. This is the quiet hero of modern travel.

But—and here’s the kicker—if you use two different cards (say, one for morning, another for afternoon because your battery died), the system treats them like two separate people. You lose the cap. Chaos. Financial heartbreak. Don’t do it. Pick a card and stick with it, like you would with a loyal pub.
What about the buses?
Buses are simpler. There’s a separate cap just for buses and trams. It’s lower, too. So if you spend your day hopping on the 73 bus like a maniac, you’ll hit the bus cap fast. Then you ride free. No zones. No drama. Just you, the bus, and that one guy eating a sandwich that smells like hope and regret.
