In the London Underground (and on the london buses) you can literally tap your contact-less debit or credit card. Just charged the cheapest rate for the route you took, which automatically caps per day or week on how much you pay, if you do multiple journeys, to be like an "all-day" or "all-week" pass.

Yup, I even got a refund the other day automatically. Not sure why as the tube wasn't really any worse than usual but hey, it was a free journey.
