I don't think that data about how frequently you pay for mass transit, is that valuable.

"This guy takes the train once early in the morning, then again in the evening", exactly like 10 million people in the city, maybe?

If that's true why would Visa/mastercard push so hard to get into so low tx ( <$1 each) processing? What are they paying/losing money for?

It's data. For some reason they're willing to pay to get a transit data for as much as possible people in several countries.
