If you don’t have a korean card I am sure you can struggle a lot since many website such as online shopping websites doesn’t allow foreign card, also some to order food some delivery companies ask to pay in advance and there is no option to pay with foreign card. If you are residing in South Korea due to work, studies or family or you have a visa that lats more than 91 days, you are available to issue your debit card.
You can check in Kakao Maps or Naver Maps the nearest bank, you can try visiting one of those banks:
What is necessary to prepare before visiting the bank, in my opinion I recommend you download the online banking apps from the bank you decide to visit inn advance since sometimes the Wi-Fi from the stores is little slow and also it can help you to avoid to the bank again, in my case I went to NH Bank and the online apps are those:
This app helps to make transfers it means to pay from one korean account to another.
Basically this app helps us to make online purchases in websites or apps also ordering food.
Necessary requirements to issue the debit card:
The processing time is around 30 ~ 45 minutes, after they check all your papers they will make you sign many papers and basically after you sign many papers how to use and the agreement of the bank to collect certain information they will print your card and your passbook
And at least NH bank they give you one special card (보안 카드) that has special codes when you will purchase something online its basically a security card
Recommendations if you plan to make a purchase online depending your mobile carrier you should download the phone verification app in my case I have KT so I have PASS app and I use also other app that is called NICE I-PIN is also to verify my identity, number and card to make online purchases.
Having a korean card has a lot of advances at least my cards both debit or credit card sometimes doesn’t work in Korea or sometimes I want to visit a 24 hours store that we can pay by ourselves and the foreign cards doesn’t work, so for me avoiding going bank and pay my insurance, buy my products such as daily care products food and ordering food in this pandemic time made my life so easy so I truly recommend to issue a korean card if you plan to stay In Korea over 6 month or 3 months, also with specific banks you can get discounts.
