Return your microchip token at the end of your journey. This will be done automatically as you exit through the station gates. The Taipei system does not use disposable paper tickets.
Acquire a Yo-Yo Card. This is an electronic, rechargeable card that will allow to you avoid the busy token machines by swiping the card at the station entrance card readers.
Move efficiently with the crowd and stay with the flow. You will notice that in Asia, people generally tend to be more comfortable crowding against each other and will even push in order to move the crowd along. While this behavior might seem rude in North America or Europe, it is the norm in Asia.
Pay attention to the LED screens. All of the cars in the Taipei system are equipped with LED screens that will list the upcoming stops. The stops are also announced in English, Chinese and Taiwanese. The platforms also contain television screens that in addition to displaying advertisements and news announce when the next train will be arriving.
Get a map of the subway system. You can download them online or acquire them at any station. Though Taipei's lines are named according to their destinations, a map is still essential for understanding how to change between the various lines.
Follow the white lines on the platforms, which indicate where to queue-up for the cars during busy periods.
