ATM use in Korea
In Korea, there's a lot of bank. The most used bank is NH bank, KB Kookmin Bank, Worri Bank, Shinhan Bank, KEB Hana Bank, Industrial Bank of Korea, Standard Chartered Bank Korea and Citi Bank. But in NH bank, they do not accept international brand in their ATM's. But all other banks above accept international brands. At least one ATM accepts international brand in each branch. So, you can just use them!!! In addition, you don't really need cash exept traditional markets because almost all stores in Korea accepts credit/debit cards
