Student ID Card

When making an account, you can set up to have your student ID card connected to the account and use your student ID card as a debit card.

The debit card that the bank will give you will most likely not be a visa/master card, hence you cannot withdraw your money outside of Korea. 

In case you have remaining money in your account when you leave Korea, either have your student ID card connected to your account beforehand, issue a different debit card (in visa or master), or download Shinhan SOL Global App to access your account overseas
