The closest shop is at 15min care ride from home.

Im currently looking at buying a Nissan Altima 2004
But back on topic: The reason they limit it to the nexon game cards, is they are sure not to lose money. There was a time where fraudulent transaction using credit card stole lot of money from Nexon. This is why they are trying to remove the usefulness of the credit card for charging. I wont be surprise if someday soon they remove it once and for all to stay with only game cards.
