Today, I will be using the machine to buy fares for the subway. This is not my first time using these machines, but I don't use them very often, and find I always forget a lot about how to do it whenever I attempt to buy new fares.
To begin with, the machine doesn't look too friendly--very grey. Fortunately, it's very clear what I have to do given the Touch to Start
text written boldly on the screen.
