One thing that shouldn't change is the Caltrain ticketing UI. The interface is simple enough to use, and it responds to user input instantly. I can select the ticket I want with four taps in about a second, where the only slowdown is the actual payment.
- I tap my Clipper card.
- A Caltrain employee checks my card about every other time I'm on a train.
- Sometimes they threaten to arrest me because I didn't tap it hard enough 3 days ago.
