Your bank has the best exchange rate! Always use a travel credit card (without foreign transaction fees) to max out points instead of a regular cc! (NEVER use debit card, unless withdrawing from ATM)
TIP: don’t exchange at the airport (they have the worse, but just a bit if you need)
→ Best to use ATM whenever needed, cash usage depends on the country
→ When selecting currency during payment ALWAYS select the local currency!
Recommeded by a friend to use a debit card with free ATM withdraws!
Japan: A LOT! for food! shopping + transportation (suica on apple wallet) is okay without
Korea: mainly transportation, street food (restraunts all take card)
Taiwan: decent amount for street food
Vietnam: DECENTLY a lot, restraunts/shopping malls take card, everywhere else low chance
