Should I exchange money at the airport?

Only as a last resort. Airport exchange counters have the worst rates — you'll lose 5-12 percent. If the ATM is broken or you arrive after hours, exchange just enough to get into town, then find an ATM.

How much cash should I carry per day?

Depends on the country. In card-friendly places like the UK or Australia, 20-30 dollars equivalent is enough. In cash-heavy countries like Japan or Vietnam, carry 60-100 dollars equivalent. Withdraw once every 3-4 days to minimize ATM fees.

What if my card gets declined abroad?

First, make sure you notified your bank. If you did and it's still declined, call the number on the back of the card immediately. It's often a fraud hold. This is why you carry two cards from different banks — if one is frozen, the other still works.

Can I use my card everywhere?

Not everywhere. Cards work in most hotels, restaurants, and shops in cities. They don't work at street markets, small guesthouses, local buses, and many taxis. Always have cash as a backup.

Should I accept the conversion when using an ATM?

No. When an ATM offers to convert to your home currency, decline it. This is called dynamic currency conversion and it costs you 3-8 percent extra. Always choose to be charged in the local currency and let your bank do the conversion.

What if I run out of cash and can't find an ATM?

Ask your hotel or hostel front desk where the nearest bank ATM is. If you're desperate, many hotels will do a cash advance on your credit card, but expect a 3-5 percent fee plus interest. This is why you always withdraw more than you think you need.

Card or Cash: Which to Use When You Travel

Use a card for most purchases and withdraw local cash from ATMs for small vendors, tips, and places that don't accept cards. Carry both, but keep most of your money on a no-foreign-transaction-fee credit or debit card. Always have 50-100 dollars worth of local currency as a backup.

Get the right cards before you leave. Apply for a credit card with no foreign transaction fees at least 3 weeks before departure. Capital One, Chase Sapphire, and Discover have good options. Get a debit card from a bank that reimburses ATM fees — Charles Schwab and Fidelity do this. Tell your banks you're traveling so they don't freeze your cards.
Arrive with some local cash. Exchange 50-100 dollars at your home bank before you go. You'll get a worse rate than an ATM, but you'll have cash the moment you land. This covers your first meal, a SIM card, or a taxi if the airport ATM is broken.
Use ATMs for cash withdrawals. Find an ATM attached to a bank, not a standalone machine in a tourist area. Withdraw the maximum amount your bank allows to minimize fees. Always decline the conversion offer and choose to be charged in local currency — you'll save 3-8 percent.
Default to card, switch to cash when needed. Pay with card everywhere it's accepted. Use cash for street food, small shops, taxis in some countries, tips, public toilets, and any vendor with a handwritten price list. If you're unsure, try the card first.
Keep your cash and cards separated. Put your main card in your wallet. Keep your backup card in your bag or hotel safe. Split your cash — carry what you need for the day, stash the rest in a different pocket or bag compartment. If you lose your wallet, you still have access to money.
Know the local cash culture. Japan and Germany still run on cash for many transactions. Scandinavia barely uses it. Southeast Asia is mixed — cities take cards, rural areas don't. Check your destination before you go and adjust how much cash you carry.
