ATM
Cards with the Plus and Cirrus logos are the easiest to use and most widely accepted in Korea. Some places even accept international cards like China UnionPay, Maestro, Electron, and JCB cards.

Banks as well as other sites have ATMs (automatic teller machines), where customers can make withdrawals, deposits, and fund transfers. However, as all ATM transactions require an account with a Korean bank, ATMs are not particularly convenient for international travelers except for getting cash advances on a credit card. If you have an account with Citibank, however, you can enjoy a more extensive range of banking services. Just visit a Citibank location nearby for ATM or counter services. Some ATM/CD machines operate 24 hours a day, while others are opened from 8am to 12am.
Public phone
There are three types of public telephones in Korea: coin-operated telephones, card phones, and credit card phones. A local call costs 70 won (US$0.06) for three minutes. Intercity calls cost considerably more. Coin phones return coins that are not charged, but do not return change for partially used 100 won coins. Card telephones can be used to make international calls as well as local and intercity calls. Telephone cards come in 2,000, 3,000, 5,000, and 10,000 denominations and are on sale in shops close to telephone boxes and in banks. There are also credit card phones, which you can use with major credit cards.
