In Seoul, you can conveniently get around by bus, subway, taxi, and more using transportation cards (T-money or Cash-bee). Transportation cards can be purchased and recharged at convenience stores and subway stations. Since a single subway ticket can only be used on the subway, if you plan to use the bus together, it's convenient to prepare a transportation card. Subway stations support language selection for charging and ticketing devices. Check your balance and available sections before boarding. Card types, charging methods, and usage conditions may change, so please check the official Seoul city information before departure.
