More than that (which is an amazing feature, don't get me wrong) is the fact that there is a single app for every public transportation system in the country.

Compare that to Italy/France/Spain (those that I know) where, depending where you are traveling to, you have to download, sign in, and give your credit card details to N different apps in different states of disrepair/being barely maintained.

Virtual credit cards (I use Revolut) that I then delete mitigate that, but still, what a mess.
