ATMs abundant but must display 'Global' logo; daily withdrawal limits typically 300,000–700,000 KRW. Request local currency to avoid dynamic conversion fees.

Works for international online shopping. South Korean sites may reject foreign cards; check merchant policy first.

Widely accepted at hotels, chain stores, restaurants, convenience stores (GS25, CU, 7-Eleven). May be declined by small local vendors or traditional markets; always ask first.
