What card to use?
We will be 1 week in Seoul and 2 days in Sokcho to do some hiking. I have been looking at the options for cards for restaurants, transportation, payments, etc., but there are so many options I can’t decide which one is best? We will be using both Visa, MC and maybe Amex. I have seen Wowpass, Lottepass, Tmoney… please let us know what you think would work best:) also how much money do you think we should have changed? We are 2 adults.
