Do I need to swipe my card to get on and off? I don't think anyone got off the bus and swiped the card.

Before getting on the bus, observe the slogan on the door. There are signs on the bus door. One is an unmanned ticketing car, and the other is a manned ticketing car. Needless to say, the ticket seller will give as much as he wants. Unmanned ticketing vehicles are divided into single fare and segmented pricing. These are all tips from the door. One-way fare does not need to be swiped. For the bus with block pricing, you need to swipe your card when you get off, otherwise you will be charged for the whole journey.
