Getting around Korea: T-money, cashless buses and Seoul's Climate Card

One prepaid card works on almost all public transport. Many buses take no cash, and since 1 October 2026 Seoul's Climate Card passes cover Seoul only.

Checked 12 October 2026

Korea is one of the few countries where a single prepaid card gets you onto buses, subways and taxis almost everywhere. For a visitor, buying one on the first day is the most useful thing you can do.

Many buses do not take cash

Korean cities have been switching buses to cashless operation. Seoul lists 183 cashless routes (January 2026), while other Seoul buses still take cash. The Korea Tourism Organization says all city buses in Incheon, Daegu and Gwangju are cashless. Free transfer rules also differ from city to city — Seoul allows up to four free transfers, Busan two.
