Korea's public transportation transfer discount system is more than just a way to reduce travel costs; it is a core system that enables fast and efficient movement. This system was first introduced in July 2004, alongside the reorganization of the public transportation network in Seoul. In the past, passengers had to pay a separate fare every time they boarded a bus or a subway. With the introduction of this system, passengers can apply a distance-proportional integrated fare system when connecting these two modes of transport.
