Payment checklist
- Cards are common, but cash is still useful for small vendors, transport card top-ups and backup.
- Cards are widely accepted in cities, restaurants, shops and hotels.
- Local payment apps may not be available to visitors, while international mobile wallets vary by terminal.
- Look for global ATM support and check fees; not every ATM works with foreign cards.
- Tipping is generally not expected in ordinary service settings.
- Decide before landing whether you need South Korean won (KRW) before leaving Incheon International Airport (ICN).
